Potato

OpenSource inline USB-PD Power meter.

...WIP...

Desired features

• Easy to assemble (No QFN)

• Read device PD capabilities

• Capture USB-PD messages

• Read USB D- / D+ voltages for QC

• Pull resistors for QC control

• UART or USB for datalogging

• Either buttons or encoder for input

• Small LCD display

• DC In/Out port

• Accelerometer or tilt switch for rotation?

Ideas to explore

• As LVGL is a goal for the UI, consider prototyping on "real" computer or talking to the PineTime team about their experience about developing UI in NaCL, allowing feedback from web users. If realized, this may allow more explorative development in a less painful environment as you can skip the slow upload/reboot cycle.
