Frequently Asked Questions
How do I wire a Lilypad CR2032 battery holder to my project?
Connect your circuit’s V+ (power) to one of the positive pads and GND (ground) to one of the negative pads. The duplicate +/− pads are provided for easier routing with wire or conductive thread.
Does this holder work for wearable e-textiles with conductive thread?
Yes—this maker-friendly Lilypad-style layout is designed for wearable and textile projects, and the robust connection points can be used for sewing with conductive thread or soldering leads.
What does the slide switch do on the CR2032 battery module?
The integrated slide switch provides simple on/off control so you can disconnect the battery when not in use, helping prevent accidental activation and extending battery life in portable builds.
Can I use this with Arduino or Raspberry Pi projects?
It can power small, low-power circuits commonly used with microcontrollers and sensors, but it is not a direct power input for every board. Check your Arduino/Raspberry Pi project’s power requirements and use an appropriate regulator or power stage if needed.
Where can I find the pinout or pad labels for this Lilypad battery holder?
Use the silkscreen markings on the PCB and the product listing photos for the exact + and − pad locations and orientation, since labeling can vary by revision.
