VoCore -> USB Relay Board

Wed Feb 11, 2015 11:08 am

Hi,

I have both a VoCore and a 4 channel USB relay board which is a FT232RL USB to UART chip with 4 relays.

I have soldered up the two wires for the USB and both the VoCore and Relay board are both running from a 5V wall wart.

The VoCore starts and connects to my WiFi no worries and I can SSH into it however it does not appear to see the USB-Serial chip even with the
kmod-usb-serial and kmod-usb-serial-ftdi modules installed.

I have attached a picture of the setup (excuse the awful soldering)
Connections have been checked with a multimeter and seem OK.
The chip is a FT232RL USB to UART.

Any suggestions?

Here is the output of dmesg:

Re: VoCore -> USB Relay Board

Fri Feb 13, 2015 4:59 pm

Everything looks correct in your module list:

usb_common 1160 1 usbcore
usbcore 107099 6 ftdi_sio
usbserial 18295 1 ftdi_sio

So at least your modules are loading properly. I suspect it's a wiring issue, i noticed there's no ground on the USB cable going to the relay board. I would start by wiring the ground on that USB cable to a ground pin on the VoCore.

If it still doesn't work. Try adding +5V on the USB cable as well.

You should see "/dev/ttyUSB0" when you do ls /dev/ttyU* when it is working.

You can then talk to it by doing:
screen /dev/ttyUSB0 115200 (change the baud rate to match the relay board if its not 115200)

Thanks

Re: VoCore -> USB Relay Board

I'll give it a shot. The DC jack is wired back to the same PSU but it's quite possible the USB -> Serial chip is powered from the USB port.

I'll let you know how I get on.

Thank you :)
