Choose a FC Cable separately, we recommend powering the RFD on your drone separately and not from the Telemetry port. The FRD radio modems require 5-6v and up to 800mA. Also available are the Aero Link adapter boards and bases.
Includes
2 x RFD868x Radio Modems
1 x Antenna, 868-900MHz Quarter wave monopole 2.1dBi
1 x Antenna, 868-900MHz Right Angle Quarter wave monopole 2.1dBi
RC PPM Passthrough with telemetry at the same time.
Fully ESD protected + filtered - Every IO port is protected and filtered.
Original SiK point to point firmware implemented.
Note: Currently due to the bandwidth limitations of the 868 modems Asynchronous Mesh and Multipoint Firmware are not officially supported for the 868X modems and correct operation of this code cannot be guaranteed

Software / GCS Support:
The software solution is an open source development called "SiK". It has been re implemented to suit the new processor architecture available on the 32bit ARM processor core. A boot loader and interface is available for further development and field upgrade of the modem firmware via the serial port. Most parameters are configurable via AT commands, Eg. baud rate (air/uart), frequency band, power levels. Integrated support for configuring the RFD900 radios is supported by APM Planner. The default settings are at 57600 baud, N, 8, 1, and 64k air data rate. The RFD868/900x manual is here: RFD900x Manual The RFD868/900x SiK software manual is here : RFD900x Peer-to-peer Manual
Software features include:
Frequency hopping spread spectrum (FHSS)
Transparent serial link
Point to Point, or Multipoint networking
Configuration by simple AT commands for local radio, RT commands for remote radio
User configurable serial data rates and air datarates
Mavlink radio status reporting (Local RSSI, Remote RSSI, Local Noise, Remote Noise)
Automatic antenna diversity switching on a packet basis in real time
Automatic duty cycle throttling based on radio temperature to avoid overheating
Compliance : The RFD868 is designed to be compliant with the following standards:
FCC Part 15.247 (Frequency hopping and digitally modulated intentional radiators)
AS/NZS 4268:2012 (Radio equipment and systems - short range devices)
The modem is designed for system integrators who will integrate the modem into their own projects and product prototypes. The user is responsible for compliance with local regulations for radio transmitters. Relevant docs for UK users IR 2030SI for The Radio Equipment Regulations 2017
