Product overview
The RadioLink PIX6 is an open-source flight controller for integration into aircraft and other vehicle systems. It supports APM and PX4 firmware, parameter encryption and project-specific function development. Its sensing architecture combines BMI088 and ICM42688-P gyroscopes with automatic changeover if the main gyroscope becomes abnormal. Software and mechanical vibration damping address high-frequency vibration. A 216MHz operating frequency, 2MB flash memory, 512K RAM and 32KB FRAM support its control architecture, while waypoint following and reviewable Dataflash logs provide mission-control and operational-record functions.
The controller measures 95.5mm × 51.5mm × 15mm and provides connections for external dual GPS, two CAN buses, telemetry, SBUS, a Spektrum DSM receiver, I2C and SPI peripherals. Main outputs connect to motors, while auxiliary outputs accommodate equipment such as lighting and external tripod steering gear. Integrated OSD displays flight and position information without a separate OSD module. Analog video transmission supports plug-and-play connection; the named DJI and Walksnail digital systems require a DiViT adapter board, with 720p/120fps video support specified for that arrangement.
The supplied configuration is a flight-controller package with a power module, buzzer, safety switch, 4G MicroSD card, mounting tape and connection cables. The power module accepts 2-12S (7.4-50.4V), detects current up to 90A and has a separate 22.5A single-ESC detection limit. Its BEC supplies 5.3±0.2V at 2A. Only one of two power-module versions is included, so the selected package must match the intended installation. Automatic return can be triggered by a switch, signal loss or voltage falling below the configured threshold; geofence settings are also supported.
