HDZero Halo H7 mit ELRS + 70A AM32

HDZero Halo H7 with ELRS + 70A AM32 is a combination of a flight controller with an integrated ELRS receiver and a powerful 70A ESC. The stack is designed primarily for high-performance 5" racing and freestyle drones powered by 3–8S LiPo batteries. The stack has a Mini size with 20×20 mm M3 mounting holes.

The flight controller features an integrated dual ELRS receiver operating at 2.4 GHz with full diversity and a TXCO crystal. It supports the Gemini mode for maximum reliability and minimal RC link latency. The core of the board is a powerful H743 processor and ICM42688 gyro. It includes a 5V/4A BEC for powering LEDs or a GPS module and a switchable 9V/3A BEC for powering video transmitters. The HDZero Halo is designed for use with digital video systems and does not include an OSD chip for analog video. The board provides connectors for ESCs and digital video transmitters, as well as 16MB of memory for blackbox logging. I2C pads are also available for connecting a compass or barometer.

The second part of the stack is the Halo 4in1 70A ESC, designed for high current loads and fast throttle response. It uses a split-board design that separates the power and control sections, improving cooling and crash resistance. Current is distributed through an integrated copper busbar and an 8-layer PCB with 3oz copper on each layer. This design minimizes voltage drop and improves responsiveness during rapid throttle increases.

The ESC supports a continuous current of 70A per motor and short bursts up to 100A. The PCB is coated with a conformal coating that protects against moisture, dust, and corrosion. The ESC runs modern AM32 firmware.

When using an 8S battery, it is recommended to use a capacitor rated for higher voltage.
