Description
The 3V coin cell and holder combination provides a reliable and highly compact power solution for miniature electronic projects. Utilising a standard CR2032 lithium battery, it is perfectly suited for low-power applications that require a steady voltage over extended periods. In educational STEM curricula, it is frequently used to provide backup power for Real-Time Clock (RTC) modules, ensuring timekeeping remains accurate when the main power is disconnected. It is also an excellent standalone power source for illuminating small wearable LED crafts, paper circuits, and lightweight robotics. The included holder features sturdy pins that can be easily integrated into a breadboard or custom PCB, giving students hands-on experience with portable power management alongside development platforms like the Arduino UNO and Magic Board.
