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

72 Our current prototypes mostly work, but there are a couple issues yet to
73 resolve. We hope to complete this design and put TeleMini v2.0 into production
