However, they don\u2019t have a lot of capacity, and they can run out pretty quickly if you\u2019re hitting them hard when developing a project. Thankfully, <a href=\"https:\/\/hackaday.io\/project\/26896-coin-cell-battery-emulator-cr2016cr2032\" target=\"_blank\">[bobricius] has just the tool to help.<\/a><\/p>\n<p>The device is simple \u2013 it\u2019s a PCB sized just so to fit into a slot for a CR2016 or CR2032 coin cell. The standard board fits a CR2016 slot thanks to the thickness of the PCB, and a shim PCB can be used to allow the device to be used in a CR2032-sized slot instead.<\/p>\n<p>It\u2019s powered via a Micro USB connector, and has a small regulator on board to step down the 5 V supply to the requisite 3 V expected from a typical coin cell. [bobricius] also gave the device a neat additional feature \u2013 a pair of pads for easy attachment of multimeter current probes. Simply open the jumper on the board, hook up a pair of leads, and it\u2019s easy to measure the current being drawn from the ersatz coin cell.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Coin cells are useful things that allow us to run small electronic devices off a tiny power source.
