I've no connection to the company, but one is on order :D

*TNC-Pi is a special version of TNC-X designed to interface directly with the Raspberry Pi computer. It can connect to the Pi either via the Pi's serial port, or via the I2C protocol. In the latter case, a single Pi can support multiple TNC-Pi's at the same time, since each TNC-Pi can be given a unique I2C address.*

( for those unfamiliar with the above, it's a Terminal Node Controller for AX25 packet radio)

Nice. I've ordered one. AX25 is pretty quiet round where I am, except for the occasional APRS chirp.

73 de VA3PID.

Hi all,
New ham here, interested in aprs, especially with open source, so the TNC-Pi looks ideal. I'm wondering how it's worked out for those of you who ordered them. The build, connecting to the Pi, etc. How are you using it? With a dedicated Raspi? Any updates greatly appreciated. I found a bunch of reviews of the TNC-X on eham, but nothing on the TNC-Pi specifically. Thanks,
Jim

Haven't built mine yet, but it looks like a well thought out through-hole build. The PCB is really nicely finished, too.

Kit is well-designed & despite not having built anything since getting my ticket, I was up and running within a day of it hitting the mat.
I'm using Xastir (and the maps are now working with the latest version of Raspbian).
I first configured a serial connection, but now use i2ckiss to connect, & have an Ultimate GPS (Adafruit) on the uart.
Still thinking how to get a decent cheap portable(12v) screen....
Oh, and a case better than a ready meal container & lid :D

Looks nice! I've been playing around packet myself(mainly working ISS packet), I don't have a proper interface cable so I've been manually keying up the mic to transmit. Does anybody happen to know of a cable assembly for the UV-5R for interfacing (if I had to, I suppose I could use the cheap earbud/mic cable that came with as a cheap solution)?

Further to my original post, I have backed the HDMIPi project on Kickstarter.
Looking forward to Xastir mobile operation :-)
