Hi, problem with "FTDI to USB-C Cable - 5V VCC-3.3V I/O" cable.

Hi,

I tried to use this cable: https://www.sparkfun.com/products/14909 to connect my arduino and Samsung Galaxy Active 3 Tab through this cable using RX and TX. But the problem is with the charging of the tablet as it has to run 24/7 with screen on.

I tried to use jumper wires to connect VCC and soldered cables straight to the tablet but with both cases i have very low amperage on charging and when the tablet is awake the charging is in negative, it only does charge in positive when the screen is switched off, but that cannot work in my usage case. Right now when tablet brightness is put on 10% i do have -0.500 until -0.800 amps on charging.

Am i doing something wrong or im not unable to use this cable in my case after all?

Any ideas how what to do or how to improve the speed of charging?

Thanks

These are not intended to be able to charge a connected device. The wires are thin and not designed to carry much current. You will need some sort of hub or splitter that allows charging.

Thanks for the answer…I have tried using HUBs but they are abit problematic, for example when there is temporary power loss they dosent start to charge after power is coming back, or they will start charging but data connection between arduino and tablet is lost after that, requires restart but that what im doing to do…to get rid of this restart needing thing.
