Purpose
- Test out different switching regulators, determine efficiency, voltage ripple, decoupling capacitance
- Test out different wire-to-board headers for current capacity and repeated use
- Test different board-to-board headers for current capacity and repeated use
- Test quality of silkscreen, solder mask, current capacity of traces
Results
- Switching regulators were tested from 10mA to 1A, up to 700mVpp ripple was observed compared to up to 500mVpp ripple (Measurement tools may have some errors)
