Yes indeed, tied to the PC via USB, and it works perfectly with winlink.

Nice work. Simple is beautiful.

I am a bit slow at this but do you then hook up the Arduino to your computer app by the USB port? I am assuming you could use this to run WinLink.

Simplicity itself; Simple schematic and protoboard view:

NPN is a 2n2222 or equivalent, arduino requires a firmware flashed onto
it with AVRdude


This is all based on the moblinkd design, and if you're a glutton for
punishment, I have a BOM for SMT build and the boards can be had from
oshpark: (yes, everything
fits UNDER an arduino nano)

its pretty easy to build a TNC for aprs with an arduino; I've done a
few. Average cost was ~$15 as one-off prototypes.
Mr. Shawn Sir,
Can you please post the BOM and design you use for your Arduino TNC? I'd be interested in putting one of these together. Thank you.
