Details
We made the Coin Cell Power board to make displays for our soldering kits at conventions, which we could power from a single USB battery bank. Now you can add fixed power to your CR2032 badges too! Also useful for badge makers to test your assembled badges.
Note: it is ONLY compatible with side-loading CR2032 battery holders like the one in the photo! It will not plug directly into top-loaders, though you can solder wires from the Coin Cell power board to their tabs.
Overview:
Plug in a 5V USB source at the USB-C connector, turn the top switch to ON, and select 5V or 3V power to your badge with the bottom switch. Plug the thicc Coin Cell Power board directly into the side-loading CR2032 holder on your badge! Each board comes with one JST PH cable so you can daisy-chain multiple Coin Cell Power boards and badges together.
Uses:
- Make a permanent display of your blinky badge by using a USB wall wart, and never have to change batteries again!
- Power multiple blinky badges daisy-chained together off of a single USB battery pack
- Are you a badge maker? Easily test your badges without having to fish a battery in and out every time.
Panel of PCBs ONLY:
These were cosmetic seconds that had blurry silkscreen and/or scratches on the pads. Each panel has 10 of these 2x normal thickness (3.2mm) bare boards, and each panel has 1-2 boards X'd out indicating they have also failed an electrical test. The X is in Sharpie and can be removed with isopropyl or acetone. Perfect for solder practice or making cyberpunk jewelry!
