Raspberry Pi Pico: your new $4 microcontroller

We’ve launched our first microcontroller-class product: Raspberry Pi Pico. Priced at just $4, it is built on RP2040, a brand-new chip developed right here at Raspberry Pi. Whether you’re looking for a standalone board for deep-embedded development or a companion to your Raspberry Pi computer, or you’re taking your first steps with a microcontroller, this is the board for you.

In a first for the microcomputer maker, the Pico is powered by a custom chip designed in house called the RP2040. The Pico board features the new chip, 2MB of flash memory, a clickable button, and a Micro USB Type B port. Here are the RP2040’s full specs:

Dual-core Arm Cortex-M0+ @ 133MHz

264KB (remember kilobytes?) of on-chip RAM

Support for up to 16MB of off-chip Flash memory via dedicated QSPI bus

DMA controller

Interpolator and integer divider peripherals

30 GPIO pins, 4 of which can be used as analogue inputs

2 × UARTs, 2 × SPI controllers, and 2 × I2C controllers

16 × PWM channels

1 × USB 1.1 controller and PHY, with host and device support

8 × Raspberry Pi Programmable I/O (PIO) state machines

USB mass-storage boot mode with UF2 support, for drag-and-drop programming
