Intro: How to Solder the F3 EVO Brushed Flight Controller
Step 1: Overview of the Board
The board is full with holes to connect motors, receiver and your all in one FPV camera. The pictures gives you an overview.
- USB port for connecting the board to your computer and tune Cleanflight, which is preinstalled
- Battery connection B+ and B-
- Motor connections M1-M4
- UART port 1-3 for AIO camera and receiver
- Buz port for the buzzer
- DSM for your spectrum satellite
Step 2: Connect Battery Lead
- Solder the black battery lead to B-
- Solder the red battery lead to B+
Step 3: Connect Motors
solder the brushed motors to board:
- M1: clockwise brushed motor (usually red wire to + pole, blue to - pole)
- M2: counterclockwise brushed motor (usually white wire to + pole, black to - pole)
- M3: counterclockwise brushed motor (usually white wire to + pole, black to - pole)
- M4: clockwise brushed motor (usually red wire to + pole, blue to - pole)
The standard Cleanflight Quad X layout is shown in the picture.
Step 4: Connect the AIO FPV Camera
- I used the UART 1 port to connect the AIO FPV camera. It provides 5V.
- Solder the black power lead of the AIO camera to -
- Solder the red power lead of the AIO camera to +
Step 5: Connect the Receiver
You have several options to connect a receiver. You can use PPM, SBUS or DSM.
- Solder the DSM plus lead to 3.3V, the minus lead to GND and the signal lead to RX3,
- In Cleanflight you need to enable UART3 as Serial RX.
PPM and SBUS Receiver:
- Solder to UART2, minus lead to GND, plus lead to + 5V and the signal lead to RX2
- In Cleanflight you need to enable UART2 as Serial RX (see pic)
