Simplifly H7 Flight Controller + 55A 4-in-1 ESC Stack

The Simplifly H7 stack pairs an STM32H743 flight controller with a 55A 4-in-1 ESC for racing, freestyle and long-range quads on 3S to 6S packs. The H7 processor has the headroom to run Betaflight, INAV or ArduPilot, so the same stack suits an acro build or a GPS-assisted cruiser.

Key features

• ICM-42688-P gyro plus a BMP280 barometer for altitude hold and GPS flight modes
• AT7456E OSD chip overlays flight data on analog video; 16MB onboard flash for Blackbox logging
• ESC rated 55A continuous and 65A burst per motor, with DShot300, DShot600 and bidirectional DShot for RPM filtering
• Five UARTs for receiver, GPS and VTX or DJI air unit, and up to eight motor or servo outputs
• Runs on 3S to 6S LiPo or Li-ion packs

The stack works with ELRS and SBUS receivers, analog VTXs and DJI digital air units. Check your frame's stack mounting pattern before ordering, and fit a low-ESR capacitor across the battery pads on 6S builds to absorb voltage spikes.
