    Adding 5v USB output ?

    Hello,
    I used to have the DPC14 colour display and it had a 5v USB out but it died on me and I got a c965 display as a replacement, but it does not have the 5v USB out. The USB output was handy as I could charge my phone, GPS, GoPro etc. Has anyone of you added a 5v USB plug to their setup? If so, please share how you did it.
    Cheers!

    Maybe purchase a step down dc-dc converter. This ones rated 60 volt: https://m.aliexpress.com/s/item/3248...0OL40#autostay

      Ok I thought I had a great idea for this but it didn't work. The yellow connector to the brake or gear sensor puts out 5v, so I thought I could just get a Y splitter and connect an old brake connector to a micro USB wire and this could power a USB battery pack which I could plug in any USB powered device. When I had it setup it looked like it was working. When I turned on the display the USB battery pack was charging and the output to the GoPro camera was powering the camera. The problem! When I try and put throttle or pedal assistant the motor puts out very little power. It moves but very slow! Any ideas?

        Try splicing from the main power line and using a step down voltage chip. Amazon has the chip for under 6 dollars. I use them in arduino projects.

          I would recommend that you buy the step down converter as I recommended above and wire it into your main power

            Ok thanks for the suggestions to use a DC to DC step down converter. I actually found one that will take 52volts and has 5v USB out: http://www.dx.com/p/15w-dc-12-24-36-...3#.WXZso8Y-Kcw
