PicoCamera is an Arduino-compatible camera library for the RP2040 / RP2350, featuring an esp32-camera aligned API and broad sensor support, such as OV2640 OV3660 and OV7670.

The API aligned with esp32-camera (esp_ prefix becomes pico_), and is based on PIO + DMA capture.

For sensor controls (sensor->set_vflip etc.), OV2640 is fairly complete (vflip/hmirror/brightness/contrast/saturation/white balance/exposure/effects/quality…); OV3660 currently implements vflip/hmirror/framesize/pixformat, OV7670 implements vflip/hmirror/whitebal/gain/exposure/colorbar — more on demand.

Requesting JPEG on a sensor without a JPEG encoder (e.g. OV7670) makes pico_camera_init() fail with PICO_CAMERA_ERR_NOT_SUPPORTED — same behavior as esp32-camera. A frame_size beyond the sensor’s maximum is clamped to the maximum with a warning instead of failing.

PicoCamera is published in the Arduino Library Manager: open Sketch → Include Library → Manage Libraries…, search for PicoCamera and click Install.

Arduino Cloud has been getting some serious upgrades behind the scenes. Dashboards can now have multiple pages, you can see the health of your whole fleet at a glance, and devices can be locked to your account (or freed up for someone else). Here’s everything that shipped.

Build dashboards with multiple pages

^{Add new dashboard pages from the left sidebar and give each one its own name, icon, position}

If you’ve ever tried to fit a real project onto one dashboard, you know the problem: every widget ends up crammed into the same view, whether it’s your greenhouse sensors or your energy monitor or both at once.

Now you can split it up. When editing a dashboard, add new pages from the left sidebar (web app only, for now) and give each one its own name, icon, and position — group by room, by system, by whatever makes sense. When viewing the dashboard, switch pages from the sidebar on the web or the switch button on the IoT Remote app.

See your whole device fleet at a glance

^{Spaces overview now shows Things, Devices, Members, and Trigger activity at a glance}

This is the big one in this release. Before, if you wanted to know something as simple as “how many of my devices are online right now,” you had to dig through the Devices page and count. Now every Space’s home page has a Statistics section with four widgets: 

1. Total Things (active vs. inactive)
2. Total Devices (online vs. offline)
3. Total Members (by role)
4. Trigger activations over a time range you can flip between 1 hour and 15 days

If you belong to more than one Space, for example: your personal Space plus an Organization, or a few Organizations at once, you also get Spaces Overview, which consolidates everything in one place: the same Statistics summed across all your Spaces, a Global Plan Usage table showing usage vs. limit for every Space so you know exactly where you’re closest to needing an upgrade, and an All Devices table listing every device you own, wherever it lives, with its status and Space. No more guessing which Space a device belongs to.

Track daily data usage before it’s a problem

^{Track daily ingested records against your plan’s limit, broken down by Thing or by Space}

Every plan comes with a Daily Ingested Records limit, but until now that number only existed on paper. 

That’s changing with a new chart in Statistics, plotting your daily ingested records (over 1D, 7D, 15D, or 30D windows) against a line marking your plan’s limit. Hover any day for the exact count and what percentage of your limit it represents, broken down by Thing in the single-Space view or by Space in Spaces Overview.

Decide who gets to claim a device next

^{A new toggle on every device’s detail page controls whether it can be claimed by another account}

This one solves two opposite problems at once. In classrooms, the same physical board gets passed from student to student, but devices were silently and permanently tied to whoever set them up first — reclaiming one meant deleting it and often filing a support ticket. In business settings, it was the reverse concern: nobody wanted a device to be too easy to reassign, since accidentally claiming a colleague’s hardware is a real risk.

The fix is a new “Lock to this account” toggle on every device’s detail page. Turn it on and the device stays permanently tied to your account; turn it off before deleting it and the next person can claim it under theirs. The default is set automatically — unlocked in Private and Education Spaces, locked in Business Spaces — but you can always override it.

Connect board to Arduino Cloud, right from Arduino App Lab

^{Provision UNO Q for Arduino Cloud directly from the Arduino App Lab’s device settings page}

If you’re building on UNO Q, registering with Arduino Cloud used to mean stepping outside Arduino App Lab to do it. Not anymore.

You can now register your UNO Q with Arduino Cloud directly from the Settings page, no need to leave Arduino App Lab. Once registered, your board is ready for IoT-enabled Apps: dashboards, remote control, fleet management, all of it, without breaking your workflow to set it up.

Fleet device management with Smart Folders

In case you missed it, we also shipped Smart Folders earlier this year, letting you organize your device fleet in Arduino Cloud instead of losing track of things as it grows. Check out that post if you haven’t already.

Get started on Arduino Cloud

Everything we just talked about is live in production right now, ready for you to test out! Here’s what we recommend trying first:

• Log in to app.arduino.cc (it’s free) 
• Check out the new Statistics section on the home page of a Space you manage
• If you have more than one Space, open Spaces Overview and see your whole footprint in one place
• Building a busy dashboard? Try splitting it into pages

The industrial world runs behind everyone else, technologically speaking. Reliability, safety, and maintenance are the biggest concerns, which means tried-and-true control solutions reign supreme. Even new facilities are full of machines that rely on tech that is several decades old. Mukesh Sankhla’s Edge Link is a DIY solution to bring that equipment into the modern era, without risky modifications.

Edge Link is a small device that fits onto a standard DIN rail inside any machine’s electrical cabinet. It can “speak” to many legacy machines and control systems via Modbus, RS-485, and more. Through those protocols, it can both receive data and send control commands — though, obviously, the specifics depend on the equipment in question.

At its most basic, Edge Link acts like an IoT gateway. It can log data and make that available on a network, so facilities managers can keep on eye on a machine’s status. It also allows for control along the same channels, if the equipment supports that. One could, for instance, remotely activate a startup routine before the morning shift gets in.

Data, such as sensor readings, transfer via MQTT messages and everything is organized through a structured UNS (Unified Namespace). That means Edge Link-equipped systems settle right into other systems that also take advantage of UNS, so they integrate nicely into the dashboards and cloud platforms a facility already uses.

But Edge Link also has real intelligence, thanks to the Arduino® UNO Q board it contains. That has the computing power to run local predictive maintenance machine learning models (built using Edge Impulse) that can make decisions on the edge — no outside network access necessary. One would need to be careful about how they implement that, but it would be ideal for tasks like safety shutdowns. For example, it could shut down machine B if it detects a problem with machine A. 

Sankhla even programmed a PLC Simulator, which has a complete Siemens S7-300 PLC digital twin to test with. Grab an UNO Q and you can use that to see how Edge Link works under different conditions.

More details on Edge Link can be found in Sankhla’s Hackster tutorial.

We’re thrilled to announce Arduino App Lab 0.10, our biggest release yet. With this update, you can now build applications alongside an AI agent that actively works on your project, not one that just answers questions about it.

Powered by MCP and integrated with App CLI, Agentic Mode understands your workspace, creates and edits files, runs your app, and interprets errors as they happen. It has deep knowledge of App Lab, Apps, Bricks, and Sketches.

Alongside Agentic Mode, App Lab 0.10 also introduces Language Server support for code completion and navigation, a streamlined way to connect your board to Arduino Cloud and a restructured Examples library.  Here’s a breakdown.

The big one: Agentic mode

^{Agentic mode and session panel in Arduino App Lab 0.10}

Open Arduino App Lab and you’ll notice a new button at the bottom of the screen “Agentic Mode.” Through its MCP integration with App CLI, it understands your workspace and actively works on your project.

If you need a reminder, MCP (Model Context Protocol) is an open standard that lets AI models interact with external tools and systems. Rather than just generating text, an MCP-connected agent can invoke tools, read state, and take actions, in this case, through Arduino App CLI.

It’s what allows Agentic Mode to go beyond simple conversation and actually operate on your project.

Agentic mode can create and edit files, run your App, stop it when needed, and interpret errors as they happen. Ask it to build a feature and you can watch it assemble the project step by step, instead of handing you a wall of code to copy and paste. Watch this demo as an example. 

Agentic Mode works on a Bring-Your-Own-Key basis: you authenticate with your AI provider of choice, keeping you in control of your API usage and costs. Claude is supported at first, with more providers coming soon.

Faster code editing with Language Server Support

Arduino App Lab 0.10 integrates a Language Server (not available in SBC Mode on UNO Q) that brings IDE-quality features to your Sketches and scripts: autocomplete, auto-formatting, hover documentation, “go to definition”, and “find all references” work across Arduino sketches, Python, HTML, CSS, and JavaScript.

^{The new Language Server allows Inline code definition}

Connect your board to Arduino Cloud, right from Settings

You can now register your Arduino^® UNO Q board with Arduino Cloud directly from the Settings page, no need to leave Arduino App Lab. Once registered, your board is ready for IoT-enabled Apps.

^{Provision UNO Q for Arduino Cloud directly from the Arduino App Lab’s device settings page.}

A clearer path through Examples

The Examples catalog has been restructured into three tiers so you always know where to start and where to go next:

1. Inspirations: more than examples, full blown Applications that showcase what the board can really do. 
2. Examples: the fundamentals, taught through focused topics like LEDs, matrices, and the Bridge API.
3. Bricks Examples:  small, interactive apps that each focus on a single Brick’s functionalities, so you can see one building block in action at a time.

Birduino is Hannah Robertson’s card-triggered audio player for [learning] the birds.

It consists of a deck of bird cards, an audio player, and a card reader. Tapping a card triggers playback of one of the vocalizations associated with that bird. You can trigger a bird-of-choice to learn its calls, or pick a random card and keep it hidden as you try to guess the bird from its call alone.

Programming the NFC tags on the bird cards to match them to their corresponding audio was straightforward, thanks to Max Mehl’s TonUINO Cards Manager project. It maps a manifest of audio files to their corresponding TonUINO-card-ready byte strings, which is then written to NFC tags to create the set of TonUINO cards.

Over the years, we have seen several tiny “omu” USB boards that share this “fits-in-a-USB-port” form factor. It started with the Tomu, based on a Silicon Labs EFM32 Cortex-M0+, followed by the Fomu with a Lattice iCE40 FPGA, Qomu with an EOS S3 Cortex-M4F MCU and FPGA, and the Somu, a tiny FIDO2 security key. Icy Electronics has now introduced Comu, another tiny development board based on the WCH CH32V203 144 MHz RISC-V MCU. While measuring just 13 x 9.4 mm (slightly smaller than a microSD card), the board still packs two white LEDs, four capacitive touch buttons, and six GPIOs exposed through test pads. It is designed for bare-metal programming, custom USB HID projects, and USB packet experimentation. Comu specifications:  MCU – WCH CH32V203V203F8 CPU – Single-core 32-bit RISC-V clocked at 144MHz Memory – 20KB SRAM Storage – 224KB Flash (64KB of 0-wait Flash and 160KB of normal Flash) [...]

Actually, these features have been there for a while now. I didn’t mention them just to make sure that the older PCB revisions are sold out and if you’re making new purchases, you’ll get the new PCBs with these features.

One of the features is a 5-pin USB header. You already have a microUSB connector so why another USB? This is because you can more easily route cables. A microUSB connector requires a microUSB plug, which requires about 2 inches or 5cm of space beyond the board’s edge. A 5-pin female header to USB-A cable with the 5-pin male header requires zero inches or cm. This makes the board fit inside smaller enclosures or leaves more space for other devices inside the enclosure.

Have a look at the following photo for a comparison:

Another feature is a header near the analog/digital input terminal block header. This header is a reorganized header from the analog/digital input terminal block. It brings out 5V, channels 3,2,1,0, and GND. This header makes it easier to connect these channels to a 4-relay module to control relays like this one (header on bottom right):

Even though these 4 channels are advertised as input channels, there are actually commands to use them as output channels! This way you can read your SDI-12 sensors and then actual relays to do irrigation or fan control all on this one board!

The following are the new instructions:
