3DR Single TTL MINI Radio Telemetry 433MHz 500mW for PIXHAWK and APM FC

3DR Single TTL MINI Radio Telemetry 433MHz 500mW for PIXHAWK and APM FC

This 3DR Radio Telemetry 433MHz 500mW Set allows you to link to a flight controller to a USB or UART equipped device such as a computer, laptop or tablet supporting a USB connection (OTG).

The new V2 radios, no longer have a separate Air/Ground module, as both transceivers can use UART or USB connections and supports both modes. The Radio set not only lets you see live data, such as live GPS position overlaid on a map, system voltage, heading, waypoint navigation even artificial horizon and so much more.

Using open source MAVlink based ground station software, you can even fly your aircraft with a joystick via your computer and update settings live! Or just use it for your DIY projects that need a wireless Serial interface. This kit offers a great low price, longer range, and superior performance. The system utilizes the 433MHz band and provides a full-duplex link using HopeRF’s HM-TRP modules running custom, open source, firmware.

Note: The reference to APM refers to the ArduPilot project, a family of open source autopilots based on the Arduino open-source computing platform, developed by 3DR and the open source community. It consists of a choice of ArduPilot Mega (APM) electronics and a range of free software versions for different vehicles and is governed by an open source creative commons license.

Important Note:  Do not turn ON the 3DR telemetry without attaching the antenna.

Note:. Product may be available with casing or without casing

Frequently Asked Questions

Is this telemetry module plug-and-play with PIXHAWK and APM?

Yes. It uses a standard TTL serial interface compatible with PIXHAWK and APM flight controllers. Simply connect the TX/RX and power pins, then configure baud rate in your ground station software.

What range can I expect with the stock antenna?

With the included omni antenna and 500mW power, you can achieve reliable telemetry links over several kilometers in open terrain. Adding a bi-directional amplifier or high-gain antenna can extend that range further.

How do I change radio settings like frequency or net ID?

Use standard AT commands over the serial link to adjust parameters such as frequency, net ID, and air data rate. Refer to the 3DR radio command reference sheet, send commands via a terminal emulator, then power-cycle the module to apply changes.
