HDZero Gamma 45A HD-Ready AIO

25.5×25.5mm for 2.5–4in Digital FPV Builds (3-6s)

The HDZero Gamma 45A HD-Ready AIO is a compact, digital-first all-in-one flight controller designed for 2.5–4 inch FPV drones using the popular 25.5×25.5mm Whoop / Toothpick mounting pattern.

Built around the STM32G473 MCU, Gamma delivers strong processing headroom for modern Betaflight features while keeping builds clean, simple, and reliable.

Integrated ExpressLRS Receiver

Gamma includes a built-in serial ExpressLRS 2.4GHz receiver, eliminating the need for a separate RX. This reduces wiring, saves space, and removes one of the most frustrating steps in small digital builds.

Designed for Digital Video

Gamma is purpose-built for digital FPV systems. A standard digital VTX plug and a protected 8V / 3A high-power BEC make it easy to run modern digital transmitters, including HDZero, DJI, Walksnail, and OpenIPC. A secondary 5V / 3A BEC is available for LEDs and peripherals.

The analog OSD chip is intentionally removed to save space and optimize the board for digital-only setups, making Gamma an excellent match for compact digital stacks using VTX's like the HDZero Whoop V2 or HDZero Freestyle V2.

High-Performance 32-bit AM32 ESC

The onboard 32-bit 4-in-1 AM32 ESC provides clean, stable power delivery and improved transient response during rapid throttle changes. Each motor output supports 45A continuous with 60A burst capability, helping reduce voltage spikes, brownouts, and component stress. Supports 3-6s batteries for high performance flying.

Builder-Friendly Layout

All motor and I/O pads are castellated and edge-mounted, making soldering easier and improving serviceability in tight frames - you can even mount the AIO upside down and still access all of the IO pads. The layout is optimized for clean wiring and straightforward integration of additional peripherals such as GPS, LEDs, or buzzers.
