Showing items 1 - 4 of 4 results.
Finally fixed the problem the h-bridge card had internal circuitry failing, a local electronic technician fixed it for a very reasonable cost.
Thanks Edward t your support was very helpful

Thanks Edward for your response, I have two trucks and switched the cards and the fault went to the oder truck. I will try to deeply check the card.
What does it mean "w.a.g."?

Fact of the week
Foundling hatches are safe, anonymous drop-off points for unwanted infants, allowing parents in crisis a way to surrender a baby safely without fear of punishment, ensuring the child is rescued and cared for. The concept started in the 12th century, was abandoned in the late 19th century, then reintroduced in 1952. It has since been adopted in many countries.
