It offers a rich set of interfaces including digital, analog, I2C, UART, and SPI pins, making it ideal for wearable and small-scale projects. Fully compatible with Arduino, MicroPython, and CircuitPython, this thumb-sized board delivers professional-grade performance in a minimalist design. ## Description XIAO RP2040 is a microcontroller using the Raspberry RP2040 chip. It runs at up to 133MHz, is built with rich interfaces in a tiny thumb size, and fully supports Arduino, MicroPython, and CircuitPython. The onboard interfaces are enough for developing multiple applications. XIAO RP2040 is a development board of the Seeeduino XIAO series. Like the Seeeduino XIAO, it is a compact board with a wide range of interfaces. The XIAO RP2040 is equipped with the Raspberry RP2040 chip (Dual-core ARM Cortex M0+ @133MHz). Powerful performance and low power, ideal for various wearable and small projects. Review: Great choice for small electronic devices - RP2040 has recently become my favorite microboard for building relatively simple and compact electronic devices (which usually contain a couple of inputs, a couple of outputs, a couple of buttons, a potentiometer or two and an I2C OLED display). For simple status signaling, it has a very bright built-in RGB LED which doesn't use any of the onboard pins, of which there is a limited number. I have already made a laser control box, a temperature control board for a custom-built 3D printer and a spot welder based on this board, and all of them work well. Sure, this board is not as powerful as Teensy 4.0, but it is not as expensive either, and noticeably more compact. Kudos for including the USB-C port, which is much more convenient than Teensy's micro USB. RP2040 can be soldered to one side of a PCB, leaving the other side completely free to run traces for other components, without pin holes getting in the way. For the types of devices I mentioned before, it has more than enough processing power. If such power is not needed, the clock speed of the CPU along with power consumption can be dialed down at compile stage, which helps RP2040 to run much longer when powered by battery. The PWM library is not what you would call an Arduino standard, but once you're familiar with it it's just as fast and capable. Overall, nice and very usable microboard. Review: Quality RP2040 - Good quality RP2040, this is the first seeed I’ve used but it worked as intended, inexpensive, and I got it in 3-4 days ## Technical Specifications | Specification | Value | |---------------|-------| | Brand | Seeed Studio | | CPU model | Cortex | | CPU speed | 133 MHz | | Installed RAM memory size | 264 KB | | Memory storage capacity | 2 MB | | Model name | XIAO RP2040 | ## Product Details - **Brand:** Seeed Studio - **CPU model:** Cortex - **Installed RAM memory size:** 264 KB - **Memory storage capacity:** 2 MB - **Model name:** XIAO RP2040 ## Images ![Seeed Studio XIAO RP2040 Microcontroller, with Dual-Core ARM Cortex M0+ Processor, Supports Arduino, MicroPython and CircuitPython with Rich Interfaces. - Image 1](https://m.media-amazon.com/images/I/51qxqFiizEL.jpg) ## Questions & Answers **Q: does this device allow 5v or 3.3v on the input and output pins?** A: Definitely not 5 volt compliant. According to the Raspberry RP2040 chip spec the maximum digital input voltage is IOVDD +0.3 VOLTS. Since the maximum IOVDD is 3.63 volts, the absolute max would be 3.93 volts. **Q: Does it come with pin connectors?** A: mine came with two sets of header pins which you must solder in place if you wish to use them. **Q: Can you use this with accelerometer to make a spirit level?** A: Sure. You would also need a display and a battery. Or use a USB cable and display on a computer. But this would be overkill if it weren't so hard to get old cheap chips these days. It's fine for a one off, but if you're thinking of production, check out things like older PIC an AT-Tiny parts. But if it's an actual spirit level you want, just buy one. If this is for inside a vehicle or robot, beware that accelerometers can only detect level in an unaccelerated frame (such as stationary, or constant speed including no turning). **Q: what board choice in Arduino for code uploading? Does not upload as Uno** A: In Auruino IDE, go to board selection, board manager and search for Seeed RP2040 boards. Download and install. Restart Arduino for it to recognize new libraries. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Great choice for small electronic devices *by G***V on 29 November 2023* RP2040 has recently become my favorite microboard for building relatively simple and compact electronic devices (which usually contain a couple of inputs, a couple of outputs, a couple of buttons, a potentiometer or two and an I2C OLED display).

So tiny that any USB cable plugged into it has to be secured as it weighs more than the MCU itself. Barely uses any power even while operating at full tilt, and absolutely just barely sips on a battery while in standby mode. You’d think that the GPIO would leave something to be desired, but given its size I wouldn’t say that’s much of an issue. If you need more pins, get an expansion board or use a different model. Super useful if you’re trying to shrink down your projects - pairs well with displays and other components from Adafruit, Waveshare, etc. ## Frequently Bought Together - Seeed Studio XIAO RP2040 Microcontroller, with Dual-Core ARM Cortex M0+ Processor, Supports Arduino, MicroPython and CircuitPython with Rich Interfaces. - Seeed Studio XIAO ESP32C3 - Tiny MCU Board with Wi-Fi and BLE for IoT Controlling Scenarios.
