Thanks keesj!
I could not get 5V on that pin, even if drawing power. Do I have to connect a usb device to negotiate a protocol first? Is there a possibility to draw 5V from that pin without usb controller? Is it okay to draw power from that pin without having a usb connection negotiated? What is the maximum rating either way?
Btw: is there a datasheet for that chip? I could not find one…
Thanks for the files. I am going through them. Is there a general overview of how extension modules go into the fairphone? I will need to convert the CAD files to SolidEdge to get a better look.
5V will be delivered to the pin with or without USB enumeration. There is, of course, a datasheet for the PMiC but it is not freely available. if you are running the official 1.1.7 release the port is not yet supported you typically will only get 3.2 volt on the power pin and, among other things like the USB phy will not properly be powered.
Hello !
Thanks for sharing this picture @TobiasF. Very cool easter wishes sending setup
About USB device compatibility, did you have a look over this FP2 thread ?
@orschiro I don’t own an FP1, but I would encourage you FP-Oners to grab an OTG cable (around 5€ on the web) and test for yourself, and why not creating a similar thread.
Great to hear you’re interested in this! If you’re going to make a qwerty keyboard for the Fairphone, I hope you’ll have better success than with TOHKBD.
