No power to circuit board?
Do this: carefully, check if the pins where you are connecting the fan to, deliver 12v. Try not to touch both pins at the same time. If you can use to a motor cable, do that. Connect the motor cable to the headers and measure, on the other end of the cable so you can be sure you are not creating a short circuit. That is easier.
If you are getting 12V that means that the fan is broken or was connected backwards and got burnt.
1) Are you able to see the WIFI network created by the DEVIA board?
2) If not: upload the test code from here and tell me how it goes: https://www.jjrobots.com/devia-control-board-test-code/
Thanks for the tips.
So I think the issue is the PCB doesn’t receive any power at all.
I’ve now checked:
- the power supply outputs 12V using a multimeter
- the pins on the bottom of the PCB directly under the power socket do not output any power (can’t measure any 12V)
- confirmed the two fan pins do not output 12V
- No wireless network is broadcast
Maybe the socket has a loose connector faulty contact that isn’t passing the power through to the PCB?
Ok I’ve managed to get it to turn on now after using another 12V power supply that I had.
Looks like the one that comes with the kit doesn’t connect to the power socket on the PCB snug.
Now to try and get the robot up and running!
