# TeleMini
This is a very small, baro-only recording dual-deploy altimeter for
model rocketry with integrated telemetry link.
-## Motivation ##
+Version 3.0 is back from fabrication and are ready for sale. Units are
+available from the [Garbee and Garbee](http://shop.gag.com) web store.
-We'd like to fly smaller rockets really high, which motivates an interest
-in both electronic deployment and radio direction finding for post-flight
-rocket recovery.
+For the latest TeleMini firmware and related ground station software, please
+visit the [AltOS](../AltOS) page on this site.
+
+Here's two photos of v3.0, top and bottom:

+## Older Versions ##
+
+[Version 1.0](v1.0). Same width (0.5 inches), but doesn't have the
+rear two mounting holes so it's a bit shorter (1.5 inches instead of
+1.67 inches).
## Artifacts ##
-The design files can be found on [git.gag.com](http://git.gag.com) in the
-project [hw/telemini](http://git.gag.com/?p=hw/telemini;a=summary).
+There is a single manual for TeleMini and all other Altus Metrum products,
+which is available in [html](../AltOS/doc/altusmetrum.html) and
+[pdf](../AltOS/doc/altusmetrum.pdf) formats.
+
+An outline of the board with drill hole locations is available in
+[pdf](../AltOS/doc/telemini-v3-outline.pdf) format.
+
+The hardware design files can be found on [git.gag.com](http://git.gag.com)
+in the project [hw/telemini](http://git.gag.com/?p=hw/telemini;a=summary).

-Initial hardware prototypes are assembled and working. Firmware is under
-development. We do not yet know what these will cost or when they might go
-into production.
