La pod
La pod is an open source STM32 PCB design by azonenberg: a 4-layer, 75 × 71 mm board with 210 components (48 distinct parts). It is built around the 296-35573-1, 497-18740-1, 296-47616-1, 296-29865-1 and more. Filed under displays & leds and test & measurement.
Open hardware test equipment
This is the umbrella repo for a lot of my T&M projects. Some will end up in separate repos.
Boards, subsystems, etc are all named after famous electrical engineers who made major contributions to the field of test equipment design.
All instruments are planned to share the same basic platform. Generally speaking, this platform will be:
* 1U rackmount, depth dependent on the specific instrument.
