1, F3_EVO_Brush revision is out of the F3 EVO SP RACING based on is based on a SP RACING F3 EVO firmware 32 brush flight control;
2, Improve the power supply input scheme, so that flight control support 1S (4.2V) and 2S (8.4V) power supply, 2S power can bring more violent flying experience. Individually designed circuit configuration, comes with Buck booster technology, or both 1S 2S power input, UART1 / 2/3 output 5V, DSM output 3.3V;
3, Using STM32F303CCT6 + MPU6500, advanced hardware platform F3 guarantee more stable flight;
4, With a large current NMOS transistors, operating current of up to 10A per channel or more. Each motor and is equipped with a freewheeling diode;
5, Support for PPM, SBUS, DSM receiver input signal;
6, With battery voltage detection and buzzer interface;
7, Support for the current world face almost all coreless motors, including the 1020 and other behemoths of the hollow cup.
1. DSM DSM receiver can solder directly to the interface 3.3V, GND, RX3, CF the software configuration UART3.
2. PPM and SBUS receiver can weld to the UART2 GND, + 5V, RX2 above, SBUS signal CF in the software configuration.
Before applying power, pay attention to the battery voltage selection:
The default shipping is 1S (4.2V); 2S first need to disconnect the short contacts 1S, 2S and then connect two pads short. Prohibit the same three pads shorted together.
