+== Introduction and Overview
+
+ Welcome to the Altus Metrum community! Our circuits and software reflect
+ our passion for both hobby rocketry and Free Software. We hope their
+ capabilities and performance will delight you in every way, but by
+ releasing all of our hardware and software designs under open licenses,
+ we also hope to empower you to take as active a role in our collective
+ future as you wish!
+
+ The first device created for our community was TeleMetrum, a dual
+ deploy altimeter with fully integrated GPS and radio telemetry
+ as standard features, and a “companion interface” that will
+ support optional capabilities in the future. The latest version
+ of TeleMetrum, v2.0, has all of the same features but with
+ improved sensors and radio to offer increased performance.
+
+ Our second device was TeleMini, a dual deploy altimeter with
+ radio telemetry and radio direction finding. The first version
+ of this device was only 13mm by 38mm (½ inch by 1½ inches) and
+ could fit easily in an 18mm air-frame. The latest version, v2.0,
+ includes a beeper, USB data download and extended on-board
+ flight logging, along with an improved barometric sensor.
+
+ TeleMega is our most sophisticated device, including six pyro
+ channels (four of which are fully programmable), integrated GPS,
+ integrated gyroscopes for staging/air-start inhibit and high
+ performance telemetry.
+
+ EasyMini is a dual-deploy altimeter with logging and built-in
+ USB data download.
+
+ EasyMega is essentially a TeleMega board with the GPS receiver
+ and telemetry transmitter removed. It offers the same 6 pyro
+ channels and integrated gyroscopes for staging/air-start inhibit.
+
+ TeleDongle v0.2 was our first ground station, providing a USB to RF
+ interfaces for communicating with the altimeters. Combined with
+ your choice of antenna and notebook computer, TeleDongle and our
+ associated user interface software form a complete ground
+ station capable of logging and displaying in-flight telemetry,
+ aiding rocket recovery, then processing and archiving flight
+ data for analysis and review. The latest version, TeleDongle
+ v3, has all new electronics with a higher performance radio
+ for improved range.
+
+ For a slightly more portable ground station experience that also
+ provides direct rocket recovery support, TeleBT offers flight
+ monitoring and data logging using a Bluetooth™ connection between
+ the receiver and an Android device that has the AltosDroid
+ application installed from the Google Play store.
+
+ More products will be added to the Altus Metrum family over time, and
+ we currently envision that this will be a single, comprehensive manual
+ for the entire product family.
