Main PCB
PCB - v3.1
Replace LDO with new footprint
Add photoresistor - request from Thomas K.
Add a 1/4w resistor for that voltage divider network
Do not intentionally place components in front of micro-USB charging port connector
LDO is OK because of low height
Move regulator caps
PCB - v3.2
Purpose: Low power ESP32 design and remove dev board, also can be used for e-ink display driver
ESP32 simple breakout module footprint
Programming port and jumpers to support programming
5 I2C ports
Breakout header for waveshare e-ink display
EEPROM NVM Module
PCB v1.0
Simple plug in module to support the EEPROM rainfall backup concept
