Works fine on Arduino Micro and Nano but a badly soldered pin.

Works well with Arduino Nano and Arduino Micro 5V controllers, providing both logic power and relay power (stock jumpers, no isolation). Unfortunately I had to downgrade it two stars because one of the connector pins wasn't soldered (pushed right through the board when I tried to put a Dupont connector on it) and I had to pause for a few minutes to start the soldering iron. Unfortunately the poor soldering at one point makes me doubt the quality of the soldering throughout the PCB.
