A simple breakout board with a CR1220 coin cell battery holder pre-soldered and broken out to 0.1″ pitch pins. Ideal for powering very low-current projects or providing battery backup for a real-time clock (RTC) module.

Comes fully assembled and tested, with a stick of 0.1″ header included so you can solder it on and plug directly into a breadboard.

Key Features

• CR1220 Holder – Accepts standard 12 mm CR1220 coin cell batteries
• Breadboard-Friendly – 0.1″ pitch header pins (included, requires soldering)
• Pre-Assembled – Battery holder soldered and tested, ready to use
• Compact – Minimal footprint for space-constrained projects

Ideal For

• Battery backup for RTC modules (DS1307, DS3231, etc.)
• Low-power wearable electronics and LED throwies
• Powering small microcontroller projects during prototyping
