USB/LiPo power supply for a solderless breadboard based on the design of Wouter Devinck.
Contains a charger with load sharing circuitry, an I2C fuel gauge and a 3.3V buck/boost regulator.
Build as prototype for the power block of another project in a useful-ish form factor.
Fuel gauge: MAX17043
Soft On/Off Button with a D-flip flop to turn off the Buck/boost converter.
Update 2016/10/11: 3 boards assembled and tested. Working as intended
One additional feature for future release is a protection against deep discharge of the battery.
At the moment the internal limits for undervoltage turnoff of the ICs is to low to protect the battery
