Power Pins

There's two power 'ports' - an input (called BAT) and an output (called 5V)

BAT - this is the battery input, it can range from 1.8V to 5V. Higher voltages will let you

draw more current and in general, are more efficient. Try to keep the wires going to

this pin nice and short - 1.5" or less is best!

GND - this is the power ground. This boost converter is not 'isolated' - the ground

input is the same as the ground output

5V - this is the boosted output. When the board is running, the voltage will be 5.2V

approximately. It may dip down to 5V as the current draw starts to go up (over

1000mA). When the board is disabled, this output is 'floating' but you should still try

not to apply a voltage to it while the board is disabled. There's a green LED connected

to this pin which will let you know when there's power output

Control Pins

There's two 'control' pins.

EN - this is the 'enable' pin. By default it is pulled 'high' to VBAT. To turn off the

booster, connect this pin to ground. The switch can be as small as you like, it is just a
