Gemini said 3DR Radio Telemetry Module Kit (433MHz 500mW) – Long-Range Data Link for APM, Pixhawk & PX4 at RoboShop BD

High-Power Long-Range Connectivity

This 500mW telemetry kit is designed to overcome the limitations of standard low-power radios. By utilizing the 433MHz band, which offers superior signal penetration through obstacles, this kit can achieve a stable line-of-sight range of over 5 kilometers (extendable with high-gain antennas). It uses the open-source SiK firmware and HopeRF’s HM-TRP modules to provide a reliable, transparent serial link for all your MAVLink data.

Real-Time Mission Control

With this kit from RoboShop BD, you can turn your laptop or Android tablet into a powerful Ground Control Station (GCS). Using software like Mission Planner or QGroundControl, you can see your drone’s live position on a map, adjust waypoints in mid-air, and even trigger functions like “Return to Launch” with a single click. The built-in error correction (ECC) can fix up to 25% of data bit errors, ensuring your telemetry remains clean even in electrically noisy environments.

Key Features
