  • F3_EVO_Brush V2.0 revision is out of the F3 EVO SP RACING based on is based on a SP RACING F3 EVO firmware 32 brush flight control.
  • the flight control support 1S (4.2V) and 2S (8.4V) power supply, 2S power can bring flying experience more violence
  • using STM32F303CCT6 + MPU6500, advanced hardware platform F3 guarantee more stable flight
  • with a large current NMOS transistors, operating current of up to 10A or more. Each machine is equipped with freewheeling diodes.
  • support for PPM, SBUS, DSM receiver input signal.
  • with battery voltage detection and buzzer interface.
  • PCBA dimensions are: 22MM * 32.5MM, PCB thickness: 1.2MM.
  • Considerations before applying power: 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.

Receiver configuration:

  • DSM DSM receiver soldered directly to the interface 3.3V, GND, RX3, CF the software configuration UART3.
  • PPM and SBUS receiver welded to the UART2 GND, + 5V, RX2 above, SBUS signal CF in the software configuration UART2.

Packing Include :

  • 1 x 90mm Frame Kit
  • 2pcs CW, 2pcs CCW 720 Coreless motor
  • 2 pairs propellers(balck+white)
