Provide the model controllers and fault description. An EFIXLAB specialist will contact you with a diagnosis and quote.
Dziękujemy! Our specialist will contact you shortly.Frequently asked questions — Pixhawk / Cube
Yes — overvoltage most commonly destroys polymer fuses or TVS diodes, which are protective elements and can be replaced. The STM32 MCU is more resilient. Send the module for diagnostics.
Yes — after IMU replacement calibration in Mission Planner or QGroundControl is required. If the IMU was not replaced, flight parameters are preserved in Flash memory and calibration is not necessary.
Yes — we have experience with custom carrier boards. Send the PCB with a block diagram description (if available). We quote the repair of every module individually.
Pixhawk Flight Controller Repair — ArduPilot and PX4 Hardware
Pixhawk flight controllers — including the original Pixhawk 1, Pixhawk 2.1 (Cube), Pixhawk 4, Pixhawk 6X, and various manufacturer variants from Holybro, CUAV, and mRobotics — form the hardware backbone of the open-source ArduPilot and PX4 autopilot ecosystems. These controllers manage multi-rotor, fixed-wing, VTOL, and ground vehicle platforms used in commercial surveying, agriculture, inspection, research, and industrial applications. The complexity of modern flight controllers makes board-level repair a specialized skill.
Common Pixhawk failures include IMU (Inertial Measurement Unit) sensor damage from vibration or crash impacts, barometric pressure sensor contamination, GPS/GNSS module receiver failures, power management unit (PMU) issues causing voltage instability, USB and serial port damage, and microSD card slot wear. The STM32 main processor rarely fails outright but supporting components — voltage regulators, CAN bus transceivers, I2C level shifters, and connector pins — can develop faults that cause intermittent behavior or sensor dropouts.
At EFIXLAB, we provide component-level Pixhawk repair. Our process includes detailed sensor testing (accelerometer, gyroscope, magnetometer calibration verification), power system diagnostics, communication port testing (UART, I2C, SPI, CAN), and GPS module evaluation. We replace failed sensor ICs, repair power regulation circuits, restore damaged connectors, and verify firmware functionality. Post-repair testing includes full sensor calibration and communication verification across all ports.
Pixhawk flight controller repair is especially valuable for customized units with specific sensor configurations, integrated carrier boards, or specialized connectors that would need to be recreated on a new unit. Repair costs typically run 30–50% of new controller purchase. All flight controller repairs include comprehensive sensor verification and our 12-month warranty — though we always emphasize that operators must independently verify flight readiness through appropriate pre-flight testing.
