This is a new initiative. On this AIO device , we abandoned the incomplete STM32F411 MCU and replaced it with the faster and more powerful STM32F722 MCU. This upgrade brought a huge change to the Race drone.

First is a change in computing speed, from 100Mhz for the F411 to 216Mhz for the F722, which brings more computation to your compact FPV and makes flying easier.

After using STM32F722 MCU, we also brought us as many as 6 groups of UART ports. Please note that the UART pads reserved on this AlO are complete, so we can add more external devices for the Race Drone. such as

GPS, vtx, dji HD, wireless parameter adjustment and other external devices

Another very big breakthrough on the AlO was to get the rated current up to 40A, which was attributed to the unique optimization of the AlO circuit by HIFIONRC engineers. Motor 1206, 1306, 1408, 1507, 1806, 2205, 2207, 2306 are recommended.
