HDZero Halo Stack with H7 FC + Integrated Gemini ELRS RX + 70A 4in1 ESC, 3–8S, BLHeli32/AM32, Plug&Play

Overview

The HDZero Halo Stack combines the Halo Flight Controller and Halo 4in1 70A ESC into a high-performance, race-ready digital FPV powertrain. Built by HDZero, pioneers in digital FPV systems, this stack is engineered for power, durability, and ease of assembly—ideal for serious racers and freestyle pilots. With plug-and-play installation, 70A continuous output per motor, an integrated Gemini ELRS diversity receiver, and low-profile compatibility with HDZero Race VTXs, this stack simplifies builds without compromising performance.

Key Features

Halo Flight Controller

• H7 Processor for ultra-fast, responsive control.

• Integrated Gemini ELRS receiver with true diversity—no external RX required.

• TXCO (Temperature-Compensated Crystal Oscillator) for consistent link quality in high-heat race conditions.

• Plug-and-play installation: No soldering needed for VTX, ESC, or RX—cables included.

• Switchable 9V/3A BEC with Betaflight control for HDZero VTX power management.

• 5V/4A BEC powers full LED setups without external regulators.

• Designed for low-profile stacking with HDZero Race VTX (v3).

• Available in MPU6000 or ICM42688 gyro versions.

• Supports Betaflight (target: HDZERO_HALO).

Halo 4in1 70A ESC

• Split-board architecture separates control and power stages for thermal performance and crash resistance.

• Built with 24 high-efficiency MOSFETs, 3oz copper across 8 PCB layers, and a rear-mounted copper bus bar for burst performance.

• Rated at 70A continuous / 100A burst (3s) per motor.

• Conformal coating for moisture, dust, and corrosion resistance.

• Dual-sided motor pads for easy and flexible soldering.

• Supports 3S to 8S LiPo (9V–40V input).

• Firmware: BLHeli32 or AM32 (selectable).

• Telemetry output supported.
