HDZero Gamma 45A HD-Ready AIO Flight Controller w/ Built-in ELRS 2.4GHz, 25.5×25.5mm, 3-6S

Overview

HDZero Gamma 45A HD-Ready AIO is an all-in-one (AIO) flight controller for 2.5–4 inch digital FPV builds using the 25.5×25.5mm Whoop / Toothpick mounting pattern. It combines an STM32G473-based FC, a 32-bit AM32 4-in-1 ESC, and an integrated serial ExpressLRS receiver to reduce wiring and simplify compact digital setups.

Key Features

• 25.5×25.5mm Whoop / Toothpick mounting pattern
• Optimized for 2.5–4 inch digital FPV builds
• STM32G473 MCU with ICM gyro
• Integrated serial ExpressLRS 2.4GHz receiver
• 32-bit AM32 4-in-1 ESC: 45A continuous / 60A burst (per output), 3-6s
• Standard digital VTX plug for digital FPV systems
• Protected 8V / 3A BEC for digital VTX power
• 5V / 3A BEC for LEDs and peripherals
• Analog OSD chip removed (digital-optimized)
• Castellated, edge-mounted motor and I/O pads for easier soldering and servicing (pads remain accessible even when mounted upside down)
