heypcb maps 11,000+ open-source hardware boards because GitHub wasn't built for hardware

heypcb.ai launched a browsable map of open-source hardware, arguing that "GitHub wasn't built for hardware" — discovering OSS hardware projects scattered across the internet still feels like searching repositories, and you usually need to know what you're looking for.

The site indexes 11,028 boards across categories like robotics, keyboards, audio, RF, IoT, retro computing, wearables and dev boards, further filtered by MCU family (STM32, ESP32, RP2040, Arduino/AVR, Raspberry Pi, FPGA and more).
