Re: <tap> <tap> is this thing on? Hello APRS!

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.
