RP2040 is a 32-bit dual ARM Cortex-M0+ microcontroller integrated circuit [1] [2] [3] 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.
The Pico 2 has 520 KB of RAM and 4 MB of flash memory and is hardware and software compatible with the original Pico. [50] The Raspberry Pi Pico 2 W was released in November 2024, with a retail price of US$7, and includes Wi-Fi (2.4 GHz 802.11n) and Bluetooth 5.2 capabilities. [51]
The microcontroller is low cost, with the Raspberry Pi Pico 2 being introduced at US$5 and the RP2350 itself costing as little as US$0.80 in bulk. The microcontroller is software-compatible with the RP2040 and can be programmed in assembly , C , C++ , Free Pascal , Rust , MicroPython , CircuitPython , and other languages.
Raspberry Pi OS is a Unix-like operating system based on the Debian Linux distribution for the Raspberry Pi family of compact single-board computers. Raspbian was developed independently in 2012, became the primary operating system for these boards since 2013, was originally optimized for the Raspberry Pi 1 and distributed by the Raspberry Pi Foundation.

Fully Arduino compatible board, that fits perfectly on a Raspberry Pi, and can be programmed through the Raspberry Pi's serial interface. It also breaks out the Raspberry Pi's SPI and I²C interfaces, or can be used as a stand-alone Arduino when powered with the external power header. Romeo 2012 [108] ATmega328 DFRobot [109]
PicoMite MMBasic supports all the hardware features of the Raspberry Pi Pico (serial, I2C, SPI, CPU clock, ADC, etc), along with built-in support for many popular add-ons for the Pico including SD cards, LCD display with a maximum resolution of 480 × 360 pixels, touch sensitive LCD screens, real-time clocks, infrared remote controls ...
Since the UART's communication protocol is simple, it can be emulated by bit banging GPIO pins in software on modern microcontrollers (e.g. Arduino [18] or Teensy [19]), or on programmable I/O state machines (e.g. Raspberry Pi Pico's PIO [20] [21] or NXP's FlexIO [22]).
