Hello,
I bought the DG600F Coin Acceptor and I am using it with a 12V power supply.
But it does not start.
When I press the A button as shown in the video, there is no response.
If you purchased the coin acceptor board directly off our website, just [fill in the form on this page with your order number and the URL to this forum post and we can replace it for you.
If you purchased from a distributor or Amazon you will need to let them know you have a defective product and arrange with them for an exchange.](Return Policy - SparkFun Electronics)
