+# TeleMini
-TeleMini version 2.0 is a small, baro-only recording dual-deploy
-altimeter for model rocketry with integrated telemetry link. The board
-form factor and features are identical to [EasyMini](../EasyMini/), with the
-addition of radio telemetry and direction finding. TeleMini is an excellent
-choice for mid-power and smaller high-power rockets, and can also be a
-cost-effective solution for booster recovery in multi-stage projects, etc.
+This is a very small, baro-only recording dual-deploy altimeter for
+model rocketry with integrated telemetry link.
+
+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.

+## 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).
