RP2040 is a 32-bit dual-core ARM Cortex-M0+ microcontroller designed by Raspberry Pi Ltd. In January 2021, it was released as part of the Raspberry Pi Pico board. [1] Its successor is the RP2350 series. [2]

Overview

Announced on 21 January 2021, the RP2040 is the first microcontroller designed by Raspberry Pi Ltd. [1] [3] The microcontroller is low cost, with the Raspberry Pi Pico being introduced at US$4 and the RP2040 itself costing US$1. The microcontroller can be programmed in assembly, C, C++, Forth, [4] Swift, [5] Free Pascal, Rust, [6] Go, [7] MicroPython, CircuitPython, [1] [8] PicoRuby, [9] Ada, [10] TypeScript [11] and Zig. [12] It is powerful enough to run TensorFlow Lite. [1]

At announcement time, four other manufacturers (Adafruit, Pimoroni, Arduino, SparkFun) were at advanced stages of their product design, awaiting the widespread availability of chips to be put into production. [13]

Hackaday notes the benefits of the RP2040 as being from Raspberry Pi, having a good feature set, and being released in low-cost packages. [14]

Multiple stepping levels of the chip have been produced. [15]

Features

The RP2040 chip is a 7-by-7-millimetre (0.28 in × 0.28 in) QFN-56EP surface-mount device (SMD) package manufactured by TSMC using its 40 nm process. [16]

For comparison with the RP2350, see RP2350 § Family comparison.

Boards

A number of manufacturers have announced their own boards using the RP2040. A selection of the growing number is here:
