I’m having trouble getting my servo drivers to work. Does it have to be battery powered or should it be able to work with microbit plugged into the computer? Is 2 AA batteries enough power for 2 motors? I have found videos about the code, and very brief videos showing it in use, but not a good all inclusive video to get started. Any help you could provide would be very appreciated.
Thanks,
Tom
Hi @mrkelly185 and welcome to our forum.
According to Kitronik Compact 16 Servo Driver Board for the BBC micro:bit – Kitronik Ltd, you should not power this via micro:bit USB but use power supply from the driver board.
I guess that how big power supply should be depends on how many motors you want to run but Kitronik recommends 3 x AA battery holder: 3x AA Battery Holder with Flying Leads – Kitronik Ltd
What problem do you actually have?
Just need 2 servo motors running right now. I don’t seem to have any power. I have a 2-battery AA pack and a 4 battery pack. With the 4 battery pack I had to cut off the port because it wasn’t one that fit the driver board. So I have 2 black wires for that pack, but it seems not to work no matter which wire I put in the plus and minus ports.
Maybe I just need to get the right battery pack.
