[aprssig] T3-Micro released

[Scott Miller]

Hi all,

The T3-Micro is now available for beta testing.  This is a full Tracker3 
(including digipeating capability) in a USB dongle form factor with an 
on-board GPS receiver.

The only external connections are the USB connector and the 3.5mm TRRS 
plug for the radio interface, so you can't use it for Garmin FMI 
operation, but it makes a very compact standalone tracker or basic TNC.

Thanks to the new pass-through option for NMEA data, you can use it with 
non-APRS applications as a USB GPS receiver, and applications like 
APRSISCE/32 that support NMEA within KISS frames can use it as a GPS 
receiver and TNC simultaneously.

For mobile applications you can run it from a cigarette lighter USB 
adapter, and for portable use it'll run off of a USB battery pack. 
There's no enclosure for it yet, and I can't guarantee there will ever 
be one that fits this version, but at least for the duration of the beta 
test period you get a GPS receiver and tracker/TNC for less than what 
some places charge for a USB GPS receiver alone.

You can buy it in our store for $65:

We've only got a handful of these boards ready to go right now, but 
we'll have another batch done in a couple of weeks.
