Holybro Transceiver Telemetry 3DR Radio V3 Set 100mW 915MHz for Pixhawk RC Drone Flight Controller

Holybro Transceiver Telemetry 3DR Radio V3 Set 100mW 915MHz for Pixhawk RC Drone Flight Controller

Description:
A Holybro Telemetry Radio is a small, light and inexpensive open source radio platform that typically allows ranges of better than 300m 'out of the box' (the range can be extended to several kilometres with the use of a patch antenna on the ground). The radio uses open source firmware which has been specially designed to work well with MAVLink packets and to be integrated with the Mission Planner, Copter, Rover and Plane.

Processing:
100mW maximum output power (adjustable) -117dBm receive sensitivity
Open-source SIK firmware (default ArduPilot firmware, can be upgraded to MAVLinkV2 firmware in QGC)
RP-SMA connector
2-way full-duplex communication through adaptive TDM UART interface
Transparent serial link
MAVLink protocol framing
Frequency Hopping Spread Spectrum (FHSS) Configurable duty cycle
Error correction corrects up to 25% of bit errors Open-source SIK firmware
Configurable through Mission Planner & APM Planner
FT230X is a USB to BASIC UART IC
 
Features:
Interchangeable air and ground modules 915MHz
Micro-USB port
6-position JST-GH connector

Specification:
Size: 28 x 53 x 10.7mm (without antenna)
Supply voltage: 5V DC (from USB or JST-GH)
Transmit current: 100mA at 20dBm
Receive current: 25mA
Serial interface: 3.3 V UART
 
Status LEDs:
The radios have 2 status LEDs, one red and one green. The meaning of the different LED states is:
Green LED blinking - searching for another radio
Green LED solid - link is established with another radio
Red LED flashing - transmitting data
Red LED solid - in firmware update mode
 
Connecting to Pixhawk4:
Use the 6 pin JST-GH connector that should have come with the radio to connect the radio to your Pixhawk4’s “Telem 1” (“Telem 2” can also be used but the default recommendation is
“Telem1”).

Connecting to PC:
Connecting the radio to your Windows PC is as simple as connecting the micro USB cable (which should have been included with the radio) to your PC. The necessary drivers should be installed automatically and the radio will appear as a new “USB Serial Port“ in the Windows Device Manager under Ports (COM & LPT). The Mission Planner’s COM Port selection drop-down should also contain the same new COM port.

Package Included:
-2 x Radio Modules with Antennas
-1 x Micro-USB Cable
-1 x Android OTG Adapter Cable
-1 x GH 6P-GH 6P cable
-1 x MLX 6P-GH 6P Cable
-2 x SMA Adapter
