I don’t know what the pinout for that particular adapter is, but it’s likely not directly compatible. From the page on that site, “6 pins for 3.3V, RST, TXD, RXD, GND & 5V.”
If this is the order of the pins, you’ll need to do some creative rewiring to get it to work with the Diavolino, since it expects a pinout compatible with the FTDI USB-TTL cable or the Adafruit FTDI Friend:
1. (Green): RTS#
2. RX
3. TX
4. Vcc (5 V)
5. CTS
6. (Black) GND
Note 1: Pin 5 (CTS) is hooked to GND on the Diavolino, so you may need to clip the “elbow” out of the right-angle header if your adapter has (one or the other) power rail there.
Note 2: The ATmega328 chip requires 4.5 V when operating at 16 MHz, so you can power the Diavolino on 5 V, but not 3.3 V.
