Seeed Studio XIAO RP2040 - The Smallest Raspberry Pi Pico Board
Getting started with microcontrollers shouldn't be complicated or expensive. The Seeed Studio XIAO RP2040 gives you the power of the Raspberry Pi RP2040 chip in the smallest possible package. A thumb-sized board that fits in your pocket and plugs straight into your project.
At its core is the dual-core Arm Cortex-M0+ processor running at up to 133 MHz, paired with 264KB of SRAM and 2MB of onboard Flash. Whether you're writing code in Arduino, MicroPython, CircuitPython, TinyGo, or Rust, this board supports them all. This makes it the ideal learning tool and rapid prototyping platform for beginners and experienced makers alike.
Despite its tiny 21 x 17.8 mm footprint, the XIAO RP2040 packs in 14 GPIO pins (11 digital, 4 analog), plus I2C, UART, SPI, and 11 PWM outputs. It also features an onboard RGB LED and reset button, and its SMD-friendly castellated edges make it easy to solder directly onto a custom PCB for production projects.
