Readytosky 3DR Radio Telemetry Kit 915Mhz Air + Ground Module Open Source for APM2.6 APM2.8 pixhawk 2.4.6 Flight controller

Description

Specification:
▶Range of several kilometers with a small omni antenna
▶Can be utilized with a bi-directional amplifier for even more range
Open source firmware
▶AT commands for radio configuration
▶RT commands for remote radio configuration
▶Adaptive go with the flow keep an eye on when used with APM
▶Based on the Hope RF HM-TRP radio module,
▶featuring an SiLabs Si1000 RF microcontroller.

Attention:

★Please make sure your baud rate is 57600 and choose the right com port when you connect.
★APM cannot connect by telemetry when you connect USB together; Pixhawk can.
★Also please you’ll want to use the usual APM and Pixhawk. It did not give a boost to other flight controller as a result of there are lots of modified port.
★It donot have intruction inside, please kindly search “3DR radio” in google or youtube then you wil find many wiki and videos such as these:

★give a boost to 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.
★preprogram these radios to the correct bod rate so you’ll be able to 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, offering a lower price, 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.
★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 imaginable through at commands.
