Raspberry Pi Pico 2 - RP2350

The Raspberry Pi Pico 2 is the next-generation microcontroller board featuring the new RP2350 chip. With double the memory, double the storage, faster ARM Cortex-M33 cores, and enhanced security features, it's a significant upgrade while maintaining compatibility with the original Pico.

The RP2350's unique dual-architecture design lets you choose between ARM Cortex-M33 cores or open-source Hazard3 RISC-V cores. The M33 cores deliver approximately twice the performance of the RP2040's M0+ cores, making the Pico 2 ideal for more demanding applications.
