Board is by default for use without ampere-meter, for enable ampere-meter alligator open onboard solder jumper !!!
This simple hack save planet :D and your wallet ....
· it is just small round piece of board
· micro USB for delivery power, cable is not included
· 3V regulator
· alligator clip holes for your multimeter to measure current
· single board with micro usb is CR2016 =1.6mm + adapter is CR2032 = 3.2mm ... EASY
· quality Gold PCB Made in USA
· if your design have not compatible holder you can connect directly to 3V output ;-)
I understand is not like real CR2032 but I believe that help in development with battery operated devices
BEST FOR USE WITH SPRING BATTERY HOLDER FOR PCB
