I've been toiling on this for around two months now, and I just put in the PCB order and parts order today. Sometime early next week, Assembly and testing will begin.

The PCB features are as follows:

12V-24V Input voltage

8A per-channel (16A Max)

Programming / Debug header

i2c header for OLED display

Input Voltage monitoring

Mosfet temperature monitoring

The software stage will hang me up a little more. Between learning the ins and outs of the ESP-32 and designing a user interface, I expect that it will be a steep climb. Nonetheless, I hope to have some sketches soon of the flow of the menu system, and the case design as well.
