Microcontrollers on test and measurement boards
Open source test and measurement boards: common questions
Where can I find open source test and measurement boards?
This page lists 39, each read from its KiCad files on GitHub: board size, layers, the full parts list and a render of the PCB, with links to the original repository.
Which microcontrollers do test and measurement boards use?
Most are built on STM32 (6), AVR/Arduino (4), ESP32 (2) and FPGA (2).
How big is a typical test and measurement board?
The median is 60.5 × 60 mm, and 46% are two-layer designs.
What is the most popular open source test and measurement board?
By GitHub stars, HaasoscopePro by drandyhaas, with 471 stars.
Can I simulate one of these test and measurement boards before building it?
Yes. HardLabs turns a board's netlist and BOM into a working simulation, so you can boot and test firmware against it with no hardware on your desk.
