Product Description

This is the ideal solution for long range telemetry or communications.  Two RFD868x-EU modems with antennas for all antenna ports.

The kit consists of:
2 x RFD868x-EU Radio Modems
1 x Antenna, 868-900MHz Quarter wave monopole 2.1dBi
1 x Antenna, 868-900MHz Right Angle Quarter wave monopole 2.1dBi
4 x Antennas, 868-900MHz Half wave dipole 3dBi
1 x FTDI USB cable

RFD868x-EU New Features:

  • New Processor, ARM 32 bit core.
  • Air data rate: 500kbit/s.
  • AES Hardware accelerated encryption. *Fully working*
  • 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

Features:

  • Long range >40km depending on antennas and GCS setup *80km demonstrated by Edge Research labs on a balloon !, 57km in India, on Dipoles.
  • 2 x RP-SMA RF connectors, diversity switched.
  • 1 Watt (+30dBm) transmit power.
  • Transmit low pass filter.
  • > 20dB Low noise amplifier, high IP3.
  • RX SAW filter.
  • All I/O ESD protected and filtered.
  • Re implemented SiK and Multipoint SiK firmware, field upgradeable, easy to configure.
  • Small, light weight.
  • Note: Not compatible with older modems

  • Weight: 14.5g
  • Mounting: 3 x M2.5 screws, 3 x header pin solder points
  • Power Supply: +5 V nominal, (+3.5 V min, +5.5 V max), ~800 mA peak at maximum power
  • Temp. Range: -40 to +85 deg C, tested operational from -73 to +123 deg C.

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
  • Error correction routines, Mavlink protocol framing (user selectable)
  • Mavlink radio status reporting (Local RSSI, Remote RSSI, Local Noise, Remote Noise)
  • Automatic antenna diversity switching on a packet basis in realtime
  • Automatic duty cycle throttling based on radio temperature to avoid overheating
