RFD900+ 의 업그레이드 버전으로, 기존 RFD900+ 와 혼용하여 사용할 수 없습니다 (호환 안됨)
RFD900+와 RFD900x 시리즈의 주요 차이점은 프로세서를 향상된 무선 송수신기와 함께 32비트 암 기반 프로세서로 교체한 것입니다.

This is the ideal solution for long range telemetry or communications. Two RFD900x modems with antennas for all antenna ports.
The kit consists of:
2 x RFD900x Radio Modems
1 x Antenna, 900MHz Quarter wave monopole 2.1dBi
1 x Antenna, 900MHz Right Angle Quarter wave monopole 2.1dBi
4 x Antennas, 900MHz Half wave dipole 3dBi
1 x FTDI USB cable
You get a cheaper price when purchasing a whole kit !
* Please note that some newer versions of the FTDI VCP driver namely version 2.12.36.1 have been reported as possibly incompatible with the FTDI cables we stock. If you are experiencing issues, we recommend reverting to version 2.12.28 or before.
* Please note the RFD900x is not compatible with the RFD900+

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 RFD900x manual is here: RFD900x Manual
The RFD900x 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 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
Compliance:
The RFD900 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.
