+# TeleMini Version 1.2 #
+
+This is a small, baro-only recording dual-deploy altimeter for 
+model rocketry with integrated telemetry link. It's different from the
+original TeleMini:
+
+ * Supports batteries from 3.7V - 12V
+ * Screw terminals for switch and external battery
+ * Large on-board flash for data recording
+ * Built-in USB connector for configuration and data download
+ * High precision and digital barometric sensor
+
+For the latest TeleMini firmware and related ground station software, please
+visit the [AltOS](../AltOS) page on this site.
