// Author: @infused-kim
//
// Description:
// PCB footprint for for molex pico ezmate connector with 2 pins. Ideal for
// battery connections.
//
// This connector was chosen over the more common JST connector, because it
// has a mated profile height of only 1.65 mm. This is lower than the Kailh
// Choc hotswap sockets.
//
// It should also be compatible with the JST ACH connector (which is almost the
// same).
//
// One downside is that there are almost no batteries that ship with this
// connector. The one exception is the Nintendo Joycon 500 mAh battery.
//
// If you want to use the common 301230 battery, you will either need to crimp
// the connector yourself or buy a pre-crimped connector that you attach to
// the battery wires (available on digikey).
