HDZero Gamma AIO – G473 FC + 45A AM32 ESC + ELRS RX

The HDZero Gamma HD-Ready AIO is built on the STM32G473 MCU, using the 25.5x25.5mm Whoop/Toothpick pattern and optimized for 2.5–4 inch drones. An integrated serial 2.4GHz ExpressLRS receiver eliminates the need for a separate RX, reducing soldering, saving space, and making builds cleaner and easier. Designed specifically for digital video systems, the Gamma includes a standard digital VTX plug and a protected 8V/3A high-power BEC to reliably support modern digital transmitters. A secondary 5V/3A rail powers LEDs, cameras, and other peripherals. The onboard 32-bit 4-in-1 AM32 ESC delivers clean, stable power to the MCU and absorbs voltage spikes during rapid throttle changes, reducing the risk of brownouts, MOSFET failures, and motor damage. Each motor output supports 45A continuous with 60A bursts, providing ample performance for high-powered micro builds. Purpose-built for digital FPV and drone soccer, the Gamma removes the analog OSD chip to save space and pairs ideally with the HDZero Whoop V2 VTX for a compact, low-profile digital stack.
