+# TeleMini
-There are two versions of TeleMini:
+This is a very small, baro-only recording dual-deploy altimeter for
+model rocketry with integrated telemetry link.
- * [Version 1.0](v1.0) — the original TeleMini, 0.5 x 1.5 inches
- * [Version 1.2](v1.2) — the new TeleMini, 0.8 x 1.5 inches
+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.
+
+For the latest TeleMini firmware and related ground station software, please
+visit the [AltOS](../AltOS) page on this site.
