Review by Anthony Lieuallen
Completely worthless. Awful construction quality, super tiny traces connect the pins. Pins are on the same side of the board as the barrel connector, so not breadboard compatible.
Worst of all, puts a tiny surface mount 10k resistor between the positive barrel pin and the VCC header pins. What am I supposed to do with that ?! (Posted on 1/14/2016)
