Description

Single TTL 3DRobotics 3DR Radio Telemetry Kit 433Mhz for APM APM2
Descriptions:
- The 3DR Radio telemetry system is designed as an open source Xbee replacement radio set, offering a lower price, longer range and superior performance to Xbee radios. It’s availabl in 433Mhz; and in the following configurations:  serial board (for the air) and USB (for the ground).
 
- The radio is a 2-way half-duplex wireless communication system with a standard TTL UART interface, based on HopeRF's HM-TRP data link modules, and custom firmware that improves upon the modules' original features and performance.
 
- The SiK firmware includes a bootloader that permits radio firmware upgrades over the serial interface, and radio firmware with configurable parameters. Firmware upgrades and configuration are fully supported in the APM Mission Planner. Configuration is also possible through AT commands.

  A good product if there is some QC on the batch

Pros:A very cheap and good model, butt there is lack of quality control.My board came with soldering residue on the capacitors and pins. Before any use Id recommend close exception of the hole module. My friends have ordered similar modules and they got a working module. MY got fried, the rezidue shorted some capacitors.
Cons:My board came with soldering residue on the capacitors and pins. Before any use Id recommend close exception of the hole module. My friends have ordered similar modules and they got a working module. MY got fried, the rezidue shorted some capacitors.
Other Thoughts:Take a good look befor pluging it in.
Bottomline:A good product if there is some QC on the batch. IF not 22,95$ down the toilet. There is no response from support.
  Perfect

Pros:It looks high quality and works just out of the box. The original parts from 3dr robotics would have set me back about fife times the money, although I think they use the same chips...
Cons:It would have been even nicer if the sender and receiver PCBs would have been wrapped in shrink tubes.
Other Thoughts:I want to use them as telemetry system for my quadcopter.
I still have to test the range when the rest of the quad parts arrive.
Bottomline:High quality and cheap in price! It's the perfect solution for me.
