RP2040-Zero, a Pico-like MCU Board Based on Raspberry Pi MCU RP2040, Mini ver.

The RP2040-Zero is a compact, low-cost development board based on the Raspberry Pi RP2040 microcontroller. Smaller than a standard Pico, it packs the same dual-core processing power into a mini form factor with USB-C connectivity and castellated edges for direct PCB mounting.

Perfect for space-constrained projects where you need RP2040 performance in a minimal footprint.
