v2 Planned Features and Use-cases!
05/31/2024 at 00:26 • 0 comments

I'm going to log improvements for a v2 here since the main description was getting overwhelmed.

I realized this project can actually serve as a good breakout board for USB, which is especially useful for doing power-profiling on usb-powered devices.
## USB Pin Breakouts
Feature: Expose VBUS, GND, D+, D- on both A and B sides as holes for ~0.6mm pin headers with isolation switches from the MCU and battery.

For example, using the Nordic Power Profiler Kit II, we can use the PPK2 as a power source if we connect the VOUT/GND to the A_VBUS/A_GND pins. Then we can log the power consumption.

This avoids the need of a separate breakout cable or powering through a non-USB port, such as in the Arduino Mega case below:
