SIYI MK15 Air Unit with SBUS, PWM, Ethernet & MAVLink Telemetry

The SIYI MK15 Air Unit is the airborne end of the SIYI MK15 link, carrying RC control, a MAVLink telemetry datalink to the flight controller and Ethernet video from an IP camera or gimbal in one module. Its 4S–14S input lets it run straight from the flight pack on agricultural spray drones and other high-voltage industrial builds, without a separate BEC. Order it as a replacement or spare air unit for an existing MK15 ground station.

Key features

• 16-channel S.Bus output (3-pin) and PWM channels 1–5 (6-pin) for the flight controller and servos.
• UART datalink (4-pin) for MAVLink telemetry to the flight controller.
• 8-pin Ethernet video input for SIYI gimbal cameras and IP cameras.
• USB-C port for firmware upgrades.
• Rated for −10 to 55°C, with 5dBi standard omni antennas.
