The Raspberry Pi Pico is the Raspberry Pi Foundation's first microcontroller board, built around its own RP2040 chip, designed in the UK. The listing describes it as the lowest cost and smallest size development board the Foundation has produced, and at its core sits a dual-core Arm Cortex-M0+ processor with a flexible clock that can run up to 133MHz.
Memory includes 264KB of SRAM and 2MB of onboard flash, which is a solid amount of memory for a microcontroller in this class, and the chip itself is available as a castellated module for direct soldering onto carrier boards, which is how some third-party designs build the RP2040 into custom hardware.
The board exposes 26 multi-function GPIO pins, with 2 SPI interfaces, 2 I2C buses, 2 UART ports, 3 12-bit ADC channels and 16 PWM channels available across them, plus an onboard temperature sensor. A standout feature is the 8 Programmable I/O state machines, which let firmware implement custom peripherals and communication protocols in software, something not usually possible on a fixed-function microcontroller.
Programming is via USB 1.1, with support for both device and host roles, and the board supports drag-and-drop programming, appearing as a USB mass storage device for simple firmware uploads. Low-power sleep and dormant modes are supported for battery-powered projects. It runs on 1.8 to 5.5VDC, operates from -20 to 85C, and measures 51mm (L) x 21mm (W) x 4mm (H).
Hobbyists, students and engineers experimenting with custom I/O protocols, low-power sensor nodes or general microcontroller projects will find the Pico's PIO feature and generous GPIO count particularly useful. The package includes the board on its own.
