Holland,
I have three dongle PCBs ordered in the coop. I can spare one if you need it, just let me know. I also have at least one PCB of the prior version of the dongle. I think the only real difference between the older and newer versions is power and activity LEDS. I believe you can add a power LED to the older version, if I remember correctly.
Let me know if you need either one of them.
