3DR Radio Telemetry Kit 433Mhz

  • Rs. 3,600.00

TECH3087 Will be in stock after

The 3DR Radio telemetry system is designed as an open source Xbeereplacement radio set, offering a lower price, longer range and superiorperformance to Xbee radios. It’s available in 433Mhz; and in the followingconfigurations: serial board (for the air) and USB (for the ground).


The radio is a 2-way half-duplex wireless communication system with astandard TTL UART interface, based on HopeRF’s HM-TRP data link modules, andcustom firmware that improves upon the modules’ original features andperformance.


The SiK firmware includes a bootloader that permits radio firmwareupgrades over the serial interface, and radio firmware with configurableparameters. Firmware upgrades and configuration are fully supported in the APMMission Planner. Configuration is also possible through AT commands.
