Holybro Kakute H7 V1.5 and Tekko32 F4 4in1 50A ESC Stack

This Holybro stack pairs the Kakute H7 V1.5 flight controller with the Tekko32 F4 4in1 50A ESC on a 30.5 x 30.5 mm mount. It suits 5-inch to 7-inch freestyle and long-range builds, and X8 cinelifters, on 4S to 6S that need an H7 processor, plenty of UARTs and a plug-in HD video port.

Key features

• STM32H743 processor at 480 MHz with the low-noise ICM-42688-P IMU and SPA06 barometer introduced on the V1.5 revision

• Six UARTs, AT7456E Betaflight OSD and a full-size microSD slot for blackbox logging

• 5V 2A and 9V 3A BECs, with a JST-SH 6-pin plug-in port for digital HD video systems

• Two 8-pin 4in1 ESC ports and eight motor outputs, ready for X8 octocopter layouts

• Tekko32 F4 ESC, 50A continuous and 60A burst per motor, with onboard current sensor and ESC telemetry

Run the stack on 4S to 6S only: the ESC is not rated for 3S or 8S, even though the flight controller accepts a wider input. The ESC has no BEC of its own, so the flight controller's regulators feed the receiver, VTX and peripherals. Flash Betaflight 4.5.2 or newer for the V1.5 sensors.
