ESP32 / Base Board

ESP32 Base Board

This is my take on a ESP32 board versatile enough to undertake many type of projects. The design started when I was looking to build my own board from scratch and be able to collect data from sensors and send them over LoRaWAN.

Features :

• Advanced battery monitoring with TI BQ27441-G1 Fuel Gauge IC (I2C)
• DC / Solar charging with TI BQ24074 1-cell Charger IC
• Configurable 4 channels ADC with TI ADS1x15 (I2C)
• LoRa / LoRaWAN capability with HopeRF RFM95W (SPI)
• 3.3V line with ON/OFF through one digital IO
• Easy to use serial header
• All ESP32 exposed through 2x20 header
