Four-axis coreless cup flight control board

1. Brief description:

This project is a coreless cup flight control based on STM32F103CBU6.

2 Application scenarios

The design background is that I have been learning about quadcopters recently, and I have an idle receiver, so I came up with this project. (The main reason is that the five-inch blood drop did not dare to mess around, so I made a smaller one, whispering ٩(•̤̀ᵕ•̤́๑)ᵒᵏᵎᵎᵎᵎ)

3. Advantages

Suitable for entry-level quadcopter, small, simple and fully functional.

4. Parameters:

1. Main control chip: STM32F103CBU6
2. Attitude detection: MPU6050
3. Communication protocol: PPM/CRSF
4. Power supply solution: ME2188C50M5G boost + ME6206A33M3G voltage regulator
5. Power interface: MICRO_USB + PH2.0/MX2.0
6. Light indication: 1 power indicator LED
7. Battery: Support 1S battery (3.7V)
8. Motor: Brush motor (recommended motor frequency: 6000)

5. Things to note:

1. This flight control board is a 4-layer board, and the firmware can be downloaded through the serial port (the SWD download port is also provided).
2. When adjusting the parameters of the BF host computer, the gyroscope direction is set to CW 90°
3. The direction pointed by the arrow is the direction of the machine head
