Stack SKYSTARS H743 BMI270 Single Gyro F100 100A FC&ESC

SKYSTARS H743 BMI270 Single Gyro 100A is a 30×30 stack for larger builds: an H743 HD2 flight controller on the STM32H743 with a single BMI270 gyro, paired with the F100 100 A 4-in-1 ESC running BLHeli_S / Bluejay. The ESC is rated for 3–8S LiPo; the FC has 8 motor outputs, 8 UARTs, a barometer, OSD, 16 MB blackbox and a 10 V / 3 A BEC for the video transmitter.

Features

• Single BMI270 gyro. The same stack is also available with dual BMI270 (Dual Gyro).
• STM32H743 runs Betaflight, INAV and ArduPilot — suitable for quads, GPS navigation builds and wings.
• 8 motor outputs and 8 UARTs: receiver, GPS, VTX and telemetry at the same time.
• 10 V / 3 A BEC for the VTX and 5 V / 3 A for peripherals.
• DJI 6-pin connector for DJI, Vista and Walksnail without soldering; AT7456E OSD for analog video.
• F100 ESC: 100 A continuous per channel, burst 100 A × 4 (up to 10 s).
• TVS diode and two 50 V 1000 µF low-ESR capacitors on the ESC.
• FC and ESC connect with an 8-pin harness; current sensor on the ESC.

Compatibility

• Mounting: both boards are 30.5×30.5 mm with M4 holes. The ESC is the larger board (58.4×57.4 mm) — check your frame's stack space against it.
• ESC firmware is BLHeli_S / Bluejay — not BLHeli_32 and not AM32. Configure it with ESC-Configurator. Bidirectional DShot (and the Betaflight RPM filter) is available on Bluejay.
• Protocols: DShot300, DShot600, PWM; bidirectional DShot.
