Pmod prbs slow
Pmod prbs slow is an open source PCB design by azonenberg: a 4-layer, 41 × 20 mm board with 43 components (18 distinct parts). It is built around the 296-35573-1. 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.
