Description: The 3DRobotics 3DR Radio is the ideal way to setup a telemetry connection between your APM and a ground station. Small, inexpensive and with great range, the 3DR radio uses an open source firmware which allows us to do things that cannot be done with other radios. Radio Features: – Very small size – Light weight (under 4 grams without antenna) – Available in 900MHz variants – Receiver sensitivity to -121 dBm – Transmit power up to 20dBm (100mW) – Transparent serial link – Air data rates up to 250kbps – Range of approx 1 mile – MAVLink protocol framing and status reporting – Frequency hopping spread spectrum (FHSS) – Adaptive time division multiplexing (TDM) – Support for LBT and AFA – 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 – Can be used with a bi-directional amplifier for even more range – Open source firmware – AT commands for radio configuration – RT commands for remote radio configuration – Adaptive flow control when used with APM – Based on the HopeRF HM-TRP radio module, featuring an SiLabs Si1000 RF microcontroller. 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) Package including:(as the main picture showed) – 1 set 915 Mhz /433mhz 100mw telemetry – 1pcs cable
