In January 2021, the Raspberry Pi Foundation introduced its first microcontroller board, the Raspberry Pi Pico. The Foundation also took a completely new path with the integrated microcontroller chip RP2040: The chip RP2040 is the foundation's first in-house development. To date, all Raspberry Pis have used a Broadcom System-on-Chip (SoC).RP2040 microcontroller chip on boardThe RP2040 has a 133 MHz synchronized dual-core arm Cortex-M0+ processor with integrated 2 MB QSPI flash memory for code and data storage. A wide range of flexible I/O options include I2C, SPI and - uniquely - Programmable I/O (PIO). These support endless possible applications.This text is machine translated.
