Overview

RP2040-Zero is a tiny, low-cost Pico-compatible microcontroller module based on Raspberry Pi RP2040 dual-core chip. Its castellated edge pads allow direct SMD surface mounting for mass production integration.

Two variants available: bare castellated module or pre-soldered pin header model for rapid breadboard prototyping
