Esp8266 Solar Breakout Board

This board provides solar power management, battery power support and GPIO breakouts to screw terminals for the ESP8266. There are sockets for onboard temperature sensor support. An onboard voltage read circuit can sample battery level. Additional connectors to attach other modules like relays.

**Limited Early Edition Board**

This board was design for low power operations on battery power with the ability for solar recharging with MPPT control. Most onboard components have the option to be disabled or toggled for low power consumption. Components also still have their GPIO pins available via terminal in case the component is not needed and access to the GPIO pin is desired. IC connectors are compatible to hook up to other component modules like the relay board.
