It offers a rich set of interfaces including digital, analog, PWM, I2C, UART, and SPI pins, making it ideal for wearable tech and small-scale projects. Fully compatible with Arduino, MicroPython, and CircuitPython, this thumb-sized powerhouse accelerates development with broad ecosystem support and a breadboard-friendly 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: This is the future - Tons of processing power in a package the size of your thumb. 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. Review: Arduino IDEで使いやすいのが良い - GPIOの数が少なくていい時はとても重宝します。I2CやUARTで外部モジュールを繋げば、小さなボードでも多彩なことに使えています。またオンボードのLEDとしてRGBのほかNeoPixelまでひとつ付いてるので、インジケーターとして便利に使えます。 開発はArduino IDEでやっています。他のRP2040ボード（RasPi Pico等）と違って、ケーブル抜き差しやBootボタンの操作をせずとも書き込みができるので、プログラムをちょこちょこ手直ししながらの実験がとてもスムーズにできます。 ## Technical Specifications | Specification | Value | |---------------|-------| | Brand | seeed studio | | CPU Speed | 133 MHz | | Connectivity Technology | I2C | | Memory Storage Capacity | 2 MB | | Model Name | XIAO RP2040 | | RAM Memory Installed Size | 264 KB | ## Product Details - **Brand:** seeed studio - **CPU Speed:** 133 MHz - **Memory Storage Capacity:** 2 MB - **Model Name:** XIAO RP2040 - **RAM Memory Installed Size:** 264 KB ## 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) ![Seeed Studio XIAO RP2040 Microcontroller, with Dual-Core ARM Cortex M0+ Processor, Supports Arduino, MicroPython and CircuitPython with Rich Interfaces. - Image 2](https://m.media-amazon.com/images/I/51MKFVVJYUL.jpg) ![Seeed Studio XIAO RP2040 Microcontroller, with Dual-Core ARM Cortex M0+ Processor, Supports Arduino, MicroPython and CircuitPython with Rich Interfaces. - Image 3](https://m.media-amazon.com/images/I/51HcAAOcjLL.jpg) ![Seeed Studio XIAO RP2040 Microcontroller, with Dual-Core ARM Cortex M0+ Processor, Supports Arduino, MicroPython and CircuitPython with Rich Interfaces. - Image 4](https://m.media-amazon.com/images/I/611QUpnVHGL.jpg) ![Seeed Studio XIAO RP2040 Microcontroller, with Dual-Core ARM Cortex M0+ Processor, Supports Arduino, MicroPython and CircuitPython with Rich Interfaces. - Image 5](https://m.media-amazon.com/images/I/51JZTWkPH0L.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 ### ⭐⭐⭐⭐⭐ This is the future *by O***N on 11 December 2023* Tons of processing power in a package the size of your thumb.
