PRODUCT DETAILS

Seeed Studio XIAO Series are diminutive development boards, sharing a similar hardware structure, where the size is literally thumb-sized. The code name "XIAO" here represents its half feature "Tiny", and the other half will be "Puissant".

Seeed Studio XIAO RP2040 is compatible with the Raspberry Pi RP2040 ecosystem as they share the same RP2040 chip. It supports multiple languages including C / MicroPython / CircuitPython. This will be a great tool for you to get started with MicroPython.

Features

  • High Performance: Powered by Raspberry Pi 2040 chip, dual-core operating up to 133 MHz, equipped 264KB of SRAM, and 2MB of onboard flash memory

  • Ultra-small Design: 21 x 17.5mm, Seeed Studio XIAO series classic form-factor, suitable for wearable devices

  • Multiple Development Interfaces: 2x buttons, 11x digital / 4x analog pins, 1x I2C interface, 1x UART port, 1x SPI port, and 1x SWD Bonding pad interface

  • Multiple Develop Platform: Support Arduino / Micropython / CircuitPython development, friendly for beginners, satisfied for electronics enthusiasts

  • Perfect for Production: Breadboard-friendly & SMD design, no components on the back

RP2040 is the debut microcontroller from Raspberry Pi. It brings signature values of high performance, low cost, and ease of use to the microcontroller space.

Seeed Studio XIAO RP2040 is based on the RP2040 chip and wrapped in a compact size with multiple interfaces like other products from the Seeed Studio XIAO series, and it's compatible with the Seeed Studio XIAO expansion board.

In addition to the powerful CPU, the Seeed Studio XIAO RP2040 has 264K SRAM and 2MB of Flash on board. Some PINs have various functions. Moreover, Seeed Studio XIAO RP2040 supports the USB Type-C interface which can supply power and download code. 1 Reset button, 1 BOOT button, 1 user-programmable RGB LED, 1 power LED, 2 status indicators, and 1 user LED are on board, allowing developers to debug their code very easily.

The robust performance makes it perfect for machine learning applications, and the tiny size allows it to be used in wearable devices, not just for prototypes but the mass production.

Starter Kit with free Course for all Electronics Neophytes and Enthusiasts

Seeed Studio has provided the Grove Starter Kit along with free and detailed courses for you quickly get started with microcontrollers and electronics, regarding all the Seeed Studio XIAO boards, promising you a great learning experience.

Not only programming but also electronics knowledge is not required, you will be taken step by step, from understanding the basic concepts to exercising the simple projects individually, finally being able to build complex, interesting, wearable projects on your own, owing a practical electronic product prototype from the course.

You can access the Seeed Studio Grove ecosystem by connecting it to the compatible Seeed Studio XIAO expansion board. We have developed more than 400 Grove modules, covering a wide range of applications that can fulfill various needs. For example, you can make an IR Remote Control Fan by connecting the Seeed Studio XIAO RP2040 with an expansion board, a Grove IR(Infrared) Receiver, a Grove - Servo, and a Grove - Mini Fan v1.1. Get started and explore the infinite possibilities of the Seeed Studio XIAO series!

Furthermore, Seeed Studio XIAO RP2040 is friendly to the communities for its strong software compatibilities, which support Arduino, Micropython, and CircuitPython. Except for the software, flexible I/O allows it to speak to almost any external device. You can also use the Thonny editor to program as if you were using Raspberry Pi Pico.

By the way, we've set up a tinyml channel on our Discord server, please click to join for 24/7/365 making, sharing, discussing, and helping each other out.

We already have 5 XIAO products based on different solutions in the Xiao family, to help you better understand the differences and choose the most suitable part for your projects, please refer to the Seeed Studio XIAO Series Page.

    Great MCU, good support for all three major languages and powerful PIO. Fantastic footprint - it's so tiny. Better arduino support than other RP2040s.

    Suggest you use the Earle Philhower arduino library over the Seeed board library though.
