This simple hack save planet :D or maybe your wallet ....

- It is just small round piece of board
- micro USB for delivery power
- 3V regulator
- alligator clip holes for your multimeter to measure curent
- single board with micro usb is CR2016 =1.6mm + adapter is CR2032 = 3.2mm ... EASY ?????I

understand is not like real CR2032 but I believe that help with development battery operated devices.

I agree with Marian (above).  Resistance of coin cells is something integral to several circuits.

Also, the Tindie price is quite high for such a simple board.

Now make the output voltage adjustable and add an adjustable series resistance, and this would be really helpful in development.
