Faulty board?

 

Hello

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.?

Thanks, Stefano

PS Sorry for my bad english language

Please make sure you connect the battery to the battery terminal, not the recharge socket. Do not try to power from a 9V smoke detector battery. Use SLA, NiMh or LiPo batteries between 6V and 12V.

Thank you, i'll do it.

You could try posting on Oddbot's wild thumper thread - there will be users of that board there.

No, the voltage of the battery is good. I have another card and it works with the same battery.

Are you using new batteries?  may just be insufficient voltage, but I have not got this board to confirm.
