Adafruit 1871 Adafruit 20mm Coin Cell Breakout with On Off Switch (CR2032)

20mm Coin Cell Breakout with On-Off Switch.

Simple but effective - this sewable breakout board has a CR2032 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.

Coin cell battery is not included.

• For low-power or battery backup projects
• 0.1in. pitch breadboard friendly breakout pins
• On-off switch
• Battery available separately
• Adafruit part no. 1871

We stock plenty of suitable CR2032 batteries.
