This board is a high current (8A) buck converter based around the TPS51386 for providing USB power to multiple devices from one board. Focused around working from a 4S Lithium Ion battery, it should work for any input voltage source from 10V-26V DC. The board also incorporates two INA219A PMICs for monitoring input & output power over I2C.
Also included in this repo is a small 4S Li-Ion battery voltage meter.
