I bought a card "Dual 15A Wild Thumper Arduino DC Motor Controller"
When I connect the battery (voltage OK) to the card the led "good battery" lights for a while and then goes off.
The "power" led is ON, the 5V output is ok, the corrent is about 40mA.
The board doesnt work.
Do I had to send the card to the seller or can I do other controls.?
PS Sorry for my bad english language
