You can now develop CR2032 or CR2016 powered devices without having to use an actual coin cell thanks to Peter Misenko’s (Bobricius) “coin cell battery emulator CR2016/CR2032”.
The USB board contains a rounded part that is compatible with CR2016 or CR2032 coin cell batteries and allows you to power your target board via USB. The board also includes holes for alligator clips to measure the current, and by extension the power consumption.
- Power Supply
- 5V via Micro USB port
- 3V regulator
- 3V + GND pins for incompatible holders
- Power measurement – 2x alligator clip holes for Amperemeter mode (the onboard solder jumper must be open)
- Dimensions – Designed for a CR2016 battery (1.6 mm thick), but an adapter can be soldered for a CR2032 battery (3.2mm thick)
The board is sold on Tindie for $19.99, but it’s currently out of stock.
