TeraVolt AeroTel 2.4 - Telemetry Radio

The AeroTel 2.4 by TeraVolt Labs is a professional, plug-and-play telemetry module powered by the industry-proven DroneBridge communication core.

While standard DroneBridge boards require manual wiring and soldering, the AeroTel 2.4 is engineered specifically for ArduPilot integration. It features a custom “mounting-friendly” PCB, pre-installed JST-GH connectors matching the Pixhawk standard, and dedicated onboard controls for mode switching.
