In programming Arduino compatible modules (Arduino Ethernet Board), you need to use a
6-pin FTDI USB to serial converter such as Arduino USB Serial adapter, Sparkfun and Adafruit FTDI-style basic USB-to-serial breakout boards.

However, we can also do that using Iteadstudio's FOCA board v2.2 with a little trick!
You'll just need to get the necessary pins from the Foca board hooked up as shown in the figure below.


When looking at the 6 unlabeled pins on the right side of the Arduino Ethernet board, starting with the top one
that is closest to the TX and RX pins, the connections to the Foca Board are as follows:
Ethernet Board | Foca Board |
---|---|
Pin 1 GND (Closest to RX/TX) | GND |
Pin 2 CTS | CTS |
Pin 3 VCC | VCCIO |
Pin 4 RXD | TXD |
Pin 5 TXD | RXD |
Pin 6 RTS | RTS |

Hello ! nice article !
I have followed your instructions but unfortunately i had a problem !
The arduino sketch can not be uploaded to the arduino ethernet board !
avrdude: stk500_getsync() attempt 1 of 10: not in sync: resp=0x00 (error)
Please help !
