APM /Pixhawk Radio Telemetry Kit 433Mhz 100mW

Description:

This Telemetry radio set allows you to link to a flight controller such as the APM 

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 navagation even artificial 

horizon and so much more, using open source MAVlink based ground station 

software (See the ArduCopter screenshot). 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 needs 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 UK legal 433Mhz 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 3DR Radio configurator and AT commands.

Interface to the module is via standard 5V-tolerant TTL serial / FT232 USB serial.
