This is a super mini voltmeter with 0.28 inch LED display. It has reverse connect protection (though it is advisable to mind your wiring). When voltage is less than 10V, two decimal places will be shown. When voltage is more than 10V, one decimal place will be shown. This voltmeter would be great for a battery readout on your next robot, or generally useful for a retro readout panel!
