12mm Coin Cell Breakout Board

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

Comes with one fully assembled and tested coin cell battery holder and a small stick of 0.1" header so you can solder it on and plug it into a breadboard.

We also have a version with an on/off switch

Note: The CR1220 battery is NOT available
