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 theRaspberry Pi RP2040 ecosystemas 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 withMicroPython.

Features

• High Performance:Powered byRaspberry Pi 2040chip, 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 ofhigh performance, low cost, and ease of useto the microcontroller space.

Seeed Studio XIAO RP2040 is based on the RP2040 chip and wrapped in a compact size withmultiple interfaceslike other products from theSeeed Studio XIAO series, and it’s compatible with theSeeed 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 itperfect for machine learning applications, and the tiny size allows it to be used in wearable devices, not just for prototypes but the mass production.
