Raspberry Pi Pico 2 - RP2350 adds more PIO, RISC-V cores

The Raspberry Pi Pico 2, priced at $5, introduces the RP2350 chip, which significantly upgrades many features of its predecessor, the RP2040. Enhancements include an extra PIO, faster clock speeds, upgraded Arm Cortex M33 cores, and additional power-efficient RISC-V cores. The device offers increased GPIO pins, SRAM, and the addition of built-in flash variants. Despite the enhancements, it uses less power, which benefits battery-operated projects. The Pico 2 maintains the same form factor, enabling easy upgrades for existing projects.
