HDZero Halo H743 Mini Flight Controller

The HDZero Halo is a top - notch, compact flight controller. Powered by the H743 MCU, it offers strong computational power for challenging FPV applications. It comes with a true diversity ExpressLRS (ELRS) receiver supporting Gemini mode, using two receivers on different frequencies to greatly improve ELRS reception and ensure stable links, a must - have for competitive pilots. To boost reliability, it has a TXCO that keeps ELRS RX performance consistent even in high - heat situations. The integrated ELRS RX simplifies quad assembly and saves money. With the Gemini ELRS RX priced at $25 and the flight controller at $65, it's a cost - effective choice. It has switchable 9V/3A BEC output for video transmitters and 5V/4A output for LED strips. Its design makes LED strip wiring easy. Built for digital video systems, it removes the analog OSD chip to cut costs and save space. It allows the HDZero Race v3 VTX to stack on it in a low - profile way, resulting in a durable and compact build. The solderless design features dedicated ESC connection sockets and easy digital VTX connectivity for quick swaps. Available in MPU6000 and ICM42688 versions to suit different pilots' needs.

Using the HDZero Halo Flight Controller is straightforward. First, make sure to choose the right version (MPU6000 or ICM42688) according to your preference. Connect the ESC using the dedicated sockets and the included cable. For the digital VTX, it's easy to connect thanks to the simple design. When powering it, use a power supply between 3S and 8S. As for the ELRS receiver, it has a 2.4GHz RF frequency. You can choose between the short and long antennas as needed. When using in high - heat environments, don't worry as the TXCO will keep the performance stable. To maintain the controller, keep it clean and dry. Avoid dropping it or exposing it to strong impacts. If you need to swap components, the solderless design allows for quick and easy changes. Check the firmware regularly and update it to the latest version (HDZERO_HALO for the flight controller and HDZero Halo FC 2.4G Gemini RX for the ELRS receiver) for the best performance.
