# TeleDongle
This is an RF interface designed primarily for use as a ground station
-interacting with a [TeleMetrum](../TeleMetrum/) altimeter on board a high
-power model rocket. The primary computer interface is USB, but async serial
-and SPI are also available as alternatives. The RF filter components are
+interacting with Altus Metrum flight computers and trackers on board high
+power model rockets. The computer interface is USB. RF filter components are
by default set for use in the vicinity of 435 Mhz, but can be altered to
support other frequency ranges.
+TeleDongle is now at version v3.0, with 5+ dB better receiver sensitivity
+than our previous models!
+
+For the latest TeleDongle firmware and related software, please
+visit the [AltOS](../AltOS) page on this site.

## Artifacts ##
+There is a single manual for most Altus Metrum products,
+which is available in [html](../AltOS/doc/altusmetrum.html) and
+[pdf](../AltOS/doc/altusmetrum.pdf) formats.

The hardware design current gEDA files are available from
[git.gag.com](http://git.gag.com) in the project
[hw/teledongle](http://git.gag.com/?p=hw/teledongle;a=summary).
For those who don't have ready access to the gEDA suite, here are pdf snapshots
of files in more easily readable form.

-This board is an integral part of a [TeleMetrum](../TeleMetrum/) system, and
-the firmware for both share common elements. More details, including full
-source code and pre-built packages can be found on the

## Future Plans ##
-We hope to fabricate an initial batch of TeleDongle v0.2 boards in
-February 2010, and intend to make both loaded circuit boards and complete
-packaged units available for sale soon.
+None! We're very happy with the TeleDongle v3.0 design.
