WiFi Telemetry Module for Pixhawk Flight Controller

Standard telemetry radios need their own pair of 433MHz or 915MHz modules and antennas, which is extra hardware a lot of bench setups and short-range test flights do not strictly need. This module skips that entirely by carrying MAVLink data over ordinary WiFi, broadcasting its own access point so a laptop or phone can connect straight to the autopilot's ground station software the same way it would join any wireless network.

The default SSID is preset so there is no manual network configuration before first use, and WPA/WPA2 security keeps that link from being open to anyone nearby. A 921600 baud rate is plenty of headroom for full telemetry streams, logs and parameter transfers, and the roughly 200 metre range covers line-of-sight testing, tuning sessions and short local flights comfortably.

Common uses are bench-testing and tuning a Pixhawk or PX4 build without wiring up a separate radio telemetry kit, quick field parameter changes from a phone or tablet, and short-range flights where a full long-distance telemetry radio would be more hardware than the job calls for.
