Description
This Telemetry radio module allows linking to a flight controller such as our Ardupilot Mega 2.6 or Multiwii AIO. It communicates via USB or UART equipped device such as a computer, laptop, or tablet supporting a USB connection (OTG).
The new V2 radios, no longer have a separate Air/Ground module, as both transceivers can use UART or USB connections and supports both modes. The Radio set not only lets you see live data, such as live GPS position overlaid on a map, 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 used for your DIY projects that need a wireless Serial interface. This telemetry kit offers a great low price, longer range, and superior performance. The system utilizes the 433MHz band and provides a full-duplex link using HopeRF’s HM-TRP modules running custom, open-source, firmware.
The SiK firmware consists of a bootloader that permits radio firmware upgrades over the serial interface. And also configuration of system parameters. APM Mission Planner supports the Firmware upgrades and configuration of the system. Configuration can also be performed through the 3DR Radio configurator and AT commands. Moreover, the Interface to the module is via standard 5V-tolerant TTL serial / FT232 USB serial. In this module, the 2Km range is only possible when used in proper weather conditions, very low air data rate, and line of sight Ground-Air. Under default settings and full transmit power on both ends the range is around 300-500 meters
