AeroSky Telemetry Module

This Telemetry radio set allows you to link to a flight controller such as our MX Pilot Mega 2.52 or Multiwii AIO via a USB equipped device such as a computer, laptop or tablet supporting a USB connection (OTG). The Radio set not only lets you see live data such as live GPS position overlaid on a map (if the flight controller has the GPS option) to system voltage, heading, waypoint navigation even artificial horizon and so much more, using open source MAVlink based ground station software. You can even fly your aircraft with a joystick via your computer and update settings live! Or just use it for your DIY projects that need a wireless Serial interface. This kit offers a great low price, longer range (approx one mile with supplied antennas) and superior performance. The system utilizes the 915Mhz band and provides a full-duplex link using HopeRF's HM-TRP modules running custom, open source, firmware.
The SiK firmware includes a bootloader that permits radio firmware upgrades over the serial interface, and configuration of system parameters. Firmware upgrades and configuration are fully supported in the APM Mission Planner. Configuration is also possible through the AT commands.
Interface to the module is via standard 5V-tolerant TTL serial / FT232 USB serial.
