RP2040 chip for Raspberry Pi Pico - ARM® Cortex®-M0+ MCU 32-Bit
The RP2040 is a high-performance, low-cost microcontroller built around two ARM Cortex-M0+ cores. It is optimized for flexibility, ease of use, and deterministic real-time performance. Unlike many microcontrollers, it includes a unique programmable I/O subsystem (PIO), allowing custom hardware interfaces without extra components.
