DESCRIPTION

Simple but effective - this breakout board has a CR1220 coin cell battery holder

soldered on, an on/off switch and 0.1" pitch breakout pins for easy connecting.

Great for powering very low-current projects, or adding a battery backup circuit to

a real-time-clock or similar. There's two ground pins, one 'switched' power pin,

and one pin that is always on.

Comes with one fully assembled and tested breakout plus a small stick of 0.1"

header so you can solder it on and plug into a breadboard.
