MCP73832 based LIPO battery charger with selectable charge current.
I made this board as a simple exercise to get to know KiCAD a bit better. It turned out quite okay :) I have a few more of them they're for sale here.
A simple jumper selects the charge current. By default this allows selecting 20mA, 100mA and 500mA but if you have a different requirement just let me know as I can easily use different resistors while assembling.
The LED indicates that the battery is being charged. If it is fully charged the LED will go off. The board ships with a green LED by default. If you prefer another color just let me know, the following are possible: blue, red, yellow, orange and green. The LED is connected with a 6.8k resistor by default avoiding the "deadly-bright-annoying-LED" symptom. If you want a brighter LED, just let me know.
