Built in sik open source firmware, and superimposed the signal strength in the mavlink, so that in the ground station can view real-time signal strength instructions
USB end uses ftdi chip, support computer, Android device OTG connection
– 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 available in 915Mhz and 433Mhz; and in the following configurations: serial board (for the air) and USB (for the ground).
– open source firmware. Interface to the module is via standard 5V-tolerant TTL serial / FTDI USB serial.
– 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 the 3DR Radio Configurator or AT commands.
