Very nice little DC volt meter boards. I did need to tweak the trim pot on the back. I paired with a USB decoy board so I can easily tell if the charger puts out 5, 9, or 12 volts. Small enough to mount on that little board. Some times smaller is better. And the price is right. Tip: if your application is between 0 and 40 VDC max, just put a jumper on the board between the points for yellow and red wires and eliminate the yellow wire. Then use red (+) and black (-) to connect to the device under test. Voila, simple. (NOTE: if your source possibly could be in excess of 40 VDC then do not use this tip).

Super handy. add toggle switch when wiring to a battery pack and you quickly see the voltage level and thus a rough idea of state of charge. Can also be re-wired for two wire operation (third wire used for V-sense) Highly recommended !!
