915MHz Radio Telemetry 100mw/500mW Wireless Transmission Module

The 3DRobotics 3DR Radio is the ideal way to setup a telemetry connection between your APM/Pixhawk and a ground station. Small, inexpensive and with great range, the 3DR radio uses an open source
"Sik" firmware which allows us to do things that cannot be done with other radios.

• Support MWC/APM/PIXHAWK/PX4 open source flight controllers, etc
• Frequency hopping spread spectrum (FHSS)
• Power: 100mW/500mW optional
• Small size, light weight
• Transparent serial link
• CP2102 USB/TTL chip
• MAVLLink protocol
• Open source firmware
• Could correct up to 25% data bit error
• Support for LBT and AFA
• Configurable duty cycle
• Can be used with a bi-directional amplifier for even more range
• Based on the HopeRF HM-TRP radio module, featuring an SiLabs Si1000 RF microcontroller.
