HDZero Halo H743 Flight Controller - MPU6000 - 20x20

The HDZero Halo is a compact 20x20mm flight controller built around the STM32H743 MCU, with a true-diversity Gemini ExpressLRS receiver built straight onto the board — a rare combination that trims a separate receiver out of the build.

Key features

• Integrated dual-SX1280 Gemini ELRS receiver with a TCXO for stable link performance even when the board runs hot.
• STM32H743 MCU at 480MHz gives plenty of headroom for Betaflight filtering and fast loop times.
• Analog-OSD-free design built to stack directly under an HDZero digital VTX, with no soldering for the VTX, receiver or ESC connections.
• Switchable 9V/3A BEC for the VTX plus a separate 5V/4A rail that can run a full competition LED setup.
• 16MB onboard blackbox and USB Type-C for logging and configuration.

Specifications

• MCU: STM32H743 (480MHz)
• Gyro: MPU6000 or ICM42688 (choose variant)
• Mounting size: 20x20mm, M4 holes (29 x 30.5mm board)
• Power input: 3S–8S
• Antenna: 2x U.FL, 2.4GHz ELRS
• BEC outputs: 9V/3A (switchable), 5V/4A, 4.5V/0.5A
• In the box: two ELRS T antennas (40 mm and 90 mm), 30 mm SH1.0 8-pin ESC cable, two antenna strain reliefs, hardware kit

With the ELRS receiver and VTX-stacking layout built in, this is a fast, low-wiring core for competitive 5-inch racing and freestyle quads running an HDZero digital system.
