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 Specifications Dimensions: * 16.5mm x 23mm x 2mm * Mounting hole distance: 10mm x 16mm * Weight: 1.5g Resources * EagleCAD PCB files on GitHub * Fritzing object in the Adafruit Fritzing library https://elecena.pl/product/22711622/12mm-coin-cell-breakout-board 2023-03-06 https://elecena.pl/product/22711622/12mm-coin-cell-breakout-board 2023-12-27 https://elecena.pl/product/22711622/12mm-coin-cell-breakout-board 2024-09-19 https://elecena.pl/product/22711622/12mm-coin-cell-breakout-board 2024-11-29 https://elecena.pl/product/22711622/12mm-coin-cell-breakout-board 2024-11-30 https://elecena.pl/product/22711622/12mm-coin-cell-breakout-board 2025-11-28 https://elecena.pl/product/22711622/12mm-coin-cell-breakout-board 2025-11-29
