# TeleMini #
-There are two versions of TeleMini:
+TeleMini version 2.0 is a small, baro-only recording dual-deploy
+altimeter for model rocketry with integrated telemetry link. It's
+currently in development, with production planned to start in the fall
+of 2013.
- * [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
+For the latest TeleMini firmware and related ground station software, please
