I have 2 data radios for 3D Robotics APM 2.5 or PIXHAWK
These radios can be used with any other electronics to transmit data over I2C databus from microcontroller and wireless to a PC or another microcontroller. I have 2 units for sale

This Radio Telemetry kit offers a great low price, longer range (approx one mile with supplied antennas) and superior performance. The system utilizes the 915Mhz or 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.

Features:
Very small size
Light weight (under 4 grams without antenna)
915Mhz frequency band, 433Mhz
Receiver sensitivity to -117 dBm
Transmit power up to 20dBm (100mW)
Transparent serial link
Air data rates up to 250kbps
Range of approx 1 mile with supplied antennas
Demonstrated range of several kilometers with a small omni antenna
Can be used with a bi-directional amplifier for even more range
MAVLink protocol framing and status reporting
Frequency hopping spread spectrum (FHSS)
Adaptive time division multiplexing (TDM)
Support for LBT and AFA
Configurable duty cycle
Built in error correcting code (can correct up to 25% data bit errors)
Open source firmware
AT commands for radio configuration
RT commands for remote radio configuration
Adaptive flow control when used with APM
Based on the HopeRF HM-TRP radio module, featuring an SiLabs Si1000 RF microcontroller.


Specs:
Band: 915MHz and 435Mhz
Antenna connectors: RP-SMA connector
Output power: 100mW (20dBm), adjustable between 1-20dBm
Sensitivity: -117dBm sensitivity
Interface: Standard TTL UART
Connection status: LED indicators


Includes:
Radio Telemetry base station (USB Connection)
Telemetry Transceiver (Pin Header)
lead set x1
Antenna x 2

This product is based on the 3DRadio Project from 3D Robotics.

Re: 3DR - Wireless DATA Radios 915MHz and 433MHz


So is that $40 for both? I noticed they are used; what did you use them with PIXHAWK, APM? Why are you getting rid of them and which site were they purchased on? I live in Waterdown and work in Mississauga and could pick up either going or coming back from work.

Thanks,
Dan

Bump - black friday special !

To answer question: yes they weee used on Pixhawk and APM autopilots.
I had to make cable adapters to switch from one to another and they worked 100%
Firmware is updated on both sets.
These were purchased on RCTimer.com 2 years ago. I purchased high power radios at $250usd from 3dr website. These units have 100mW power which is good upto 500meters. Great For drones but not enought for airplane unless you use custom directional antennas.
