RTF Pixel Led Ring + FTDI Basic: connexion?


I just bought a FTDI Basic from Unmanned Tech and I have a question regarding the connection to the RTF Pixel Led Ring. If I look the labelled pins, I have DTR-TXO-RX1-VCC5-GND-GND on the RTF Pixel side and 3V3-RTS-TXD-RXD-GND-5V on the FTDI Basic side. Can connect them directly to program the Led Ring or do I need a special cable?

Thanks in advance for your help…

With kind regards,


I have found some information on the net and I connected both items the following way:

5V => VCC5
TXD => RX1
RXD => TX0

DTR, 3V3, RTS and the last GND were left unconnected.

I tried to upload to the Arduino-Atmel board of the RTFpixel Led Ring, but get the following error:

avrdude: stk500_recv(): programmer is not responding
avrdude: stk500_getsync() attempt 1 of 10: not in sync: resp=0x00

Anyone has an idea what’s going on or a link where I could find a tutorial how to program those led rings?

Thanks in advance for your help…


Anyone knows which board and which programmer I have to choose in the Arduino IDE?

Regarding the connexion, normally DTR should go to DSR and RTS to CTS.
The only cable left are DTR/GND on the RTF pixel led ring and 3V3/RTS on the FTDI basic side.
Do I leave those cables unconnected?
