Perfeito, precisão boa.
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).
Tips:For questions about your order, place of delivery, product discount, taxation, delivery time, warranty, shipping, payment, exchange rate, and other questions unrelated to the product, please contact customer service.
