Microcontrollers

This collection features salvaged, reclaimed, and certified open-source microcontroller boards and microprocessors sourced from retired maker spaces, engineering labs, and production prototypes.

Instead of sitting in a drawer gathering dust, these boards have been rescued, inspected, and prepared for their next project. Whether you are building a smart home automation gateway, learning embedded C++ or MicroPython, or stocking up on cost-effective components for a classroom, our salvaged inventory delivers authentic open-source power at a fraction of retail pricing.
