Description

This PCB handles power to the ESP32 module (The one with 28mm of width, with header to header separation of 25mm) via a 3.7V single cell LiPo Batery. It regulates 3.3V with a step down converter making the AMS1117 basically useless for a enhanced efficiency.
I also added an optional 12V step up regulator for a passsive 85dB buzzer output or straight 12V power output. The PCB also adds a GPS and SIM compatiblity through a UART interface with the popular modules. And a ADC input for battery measurement. I also added a trigger input with a modified jack plug (it does NOT do audio).

A render of the final product.
