Skydroid S2 Flight Controller Avionics Package (BMI088, 2-18S)

The Skydroid S2 is a flight control avionics package for industrial unmanned craft: multirotors from 3 to 8 axes, fixed-wing, VTOL fixed-wing, ground vehicles and boats. It pairs an automotive-grade BMI088 IMU with an LPS22HB barometer and accepts 2S–18S power, so one controller platform covers anything from a small survey quad to a heavy agricultural sprayer.

Key features

• BMI088 inertial sensor with low noise and drift, and stable behaviour across temperature changes
• Up to 12 PWM outputs for large multirotors and fixed-wing control surfaces
• SBUS input and output, GPS/compass serial port, two data-link ports, CAN1 and CAN2, an obstacle-avoidance interface and Type-C
• Works with any receiver that offers an S.Bus output and a data-transmission port
• Multiple built-in protection functions; set up and tuned in the Skydroid Fly ground-station app
• Open platform for secondary development
