3DR 500MW Radio Telemetry Kit 915Mhz 915 Kit Air Features

• Upgraded version: From November 2021, data transmission will be upgraded from 100mw to 500mw. Support OTG of Android Cellphones,and computer OTG. Antenna is 5.8G,not the cheap 2.4G (whose range is very small and material is very cheap) like others

• 3DR telemetry 915mhz set for multiwii setting. PLUG AND PLAY. Pre-configered and tested to 115200 BAUD rate, and all other settings needed

• 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

• 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.

About 3DR 500MW Radio Telemetry Kit 915Mhz 915 Kit Air

The default baud rate of the Radio Telemetry is 57600, not 115200. Select the correct COM port and do not select AUTO These products are DIY products, if have any problem ,like technical issues, pls kindly contact us, we are pleasure to provide you the best service ,thanks. Features: *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. *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. - 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.
