Description
Readytosky 3DR 500MW Radio Telemetry Kit 915Mhz Air and Ground Data Transmit Module for Standard Version APM2.6 APM2.8 Pixhawk Flight Controller
Very good quality design,as you can see as the picture.
Support OTG of Android Cellphones,and computer OTG. Antenna is 5.8G level ,not the cheap 2.4G level (whose range is very small and material is very cheap) like others.
– I preprogram these radios to the correct bod rate so you can just connect them to your quadrino and start chaning PID’s on the fly.
– The 3DR Radio telemetry system is designed as an open source Xbee replacement radio set, longer range and superior performance to Xbee radios. It’s availabl in 915Mhz; 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.
– Configurable duty cycle
– Built in error correcting code (can correct up to 25% data bit errors)
– Demonstrated range of several kilometers with a small omni antenna
– Open source firmware
– AT commands for radio configuration
– RT commands for remote radio configuration
– Adaptive flow control when used with APM
– Based on HM-TRP radio modules, with Si1000 8051 micro-controller and Si4432 radio module
