Pico

The Raspberry Pi Pico is a low-cost, high-performance microcontroller board built around the RP2040 chip. RP2040 features a dual-core Arm Cortex-M0+ processor with 264kB internal RAM and support for up to 16MB of off-chip flash. A wide range of flexible I/O options includes I2C, SPI, and - uniquely - Programmable I/O (PIO). These support endless possible applications for this small and affordable package.

A Raspberry Pi Pico is programmed using MicroPython, C, or C++ and, unlike other Raspberry Pi devices, doesn’t run Linux or support removable storage. Instead, Raspberry Pi Pico is programmed by flashing binaries to the on-board flash memory.

There are two generations of the Raspberry Pi Pico series:

  1. Raspberry Pi Pico (Pico 1)

  2. Raspberry Pi Pico 2

Each generation is available in four variants, which differ based on:

Wireless connectivity. Variants that include the W suffix in the name include Wi-Fi and Bluetooth.

Presoldered headers. Variants are available either as castellated modules (for direct soldering) or with presoldered pin headers.
