Description
Geu Puentes-Conde and co-authors wrote a 2026 paper on a low-cost device for testing electronic circuit boards. Factories test boards in two ways: in-circuit tests check each part, and functional tests check the whole board at work. Standard test rigs are costly, which puts them out of reach for small firms and in-house labs.
The team's design packs many test functions onto a modular board set run by a small controller chip. It can apply set voltages, switch signals through relays, and measure voltage, current, resistance, and capacitance. Working prototypes were built and run in automated test setups to prove they work. All design files, from drawings to firmware and parts lists, are shared openly. The paper aims to make board testing cheap and easy to copy.
