need to use this jumper had reconfigured your Pigtail.
Jumper 1
: Jumper #1 loops the CTS and RTS pins on the RS-232 connection. This jumper was
added because Kenwood radios require RTS pin to be high before it will respond to commands.
By looping CTS back to RTS we can fool the radio into thinking it's getting the signal from the
Pigtail. The wi-fi module does have CTS and RTS however space was limited to get the traces
so this compromise was made and works great.
Piglet
There are no jumpers in the Piglet. They have been replaced with a 3 position DIP switch. On
the PCB, around the base of the DIP switch, in white letters, are indications of what each switch
does. The three switches are for Pin 4 Power (Old Jumper 3), CTS/RTS Loop (Old Jumper 1),
and ADHOC (Old Jumper 2). Please see the jumper text above to understand what these three
connections do.
GPIOs
Only v2 and later Pigtail PCBs have the GPIO pins broken out to the board. The Piglet
has no GPIOs brought out. GPIOs are not present on the currently shipping Piglet.
If you decide to play with the GPIO pins, refer to the following mapping of Pigtail Pin to Wi-Fi
Module pin. Please refer to the Wi-Fi Module User's Guide for more information on using these
pins.
