NAZE32 flight control

Personally, I recommend the V2 version . Compared with the V1 version, V2 has improved:
1. The MicroUSB interface is replaced by a Type-C interface; 2.
BAT54C rectifier is used between USB power supply (about 5.2V) and external 5V power supply;
3. ESC The interface is replaced from 3*6P pin header to 1*8P pad;
4. Add 1*4P pad for communication serial port and its SH1.0 socket;
5. Add FLASH on the board for black box function.

The BMP280 barometer part, CP2104 serial communication part, and SPI FLASH part are all optional parts .

If a certain function is not used, this part of the circuit does not need to be soldered to reduce costs and manufacturing difficulty.

The BMP280 barometer part and the CP2104 serial communication part are shown in the figure below. This version of the PCB does not add the SPI FLASH part.

The BMP280 barometer is used to measure the altitude information of the drone and achieve functions such as height determination. The flight control can be used normally without this part.

The CP2104 serial communication part is used for serial communication between the flight control and the ground station (computer-side configuration software) and firmware burning. If you have a USB-TTL downloader, you can not solder this part of the circuit and connect the three GRT pads with flying wires to the USB-TTL downloader:

G->GND

R->TXD

T->RXD

5->5V

For convenience, it is recommended to solder the CP2104 serial communication circuit.

The CP2104 serial communication part is used for serial communication between the flight control and the ground station (computer-side configuration software) and firmware burning. If you have a USB-TTL downloader, you can not solder this part of the circuit and connect the G-5-RT cable interface to the USB-TTL downloader using an SH1.0 cable:

G->GND

R->TXD

T->RXD

5->5V

The SPI FLASH part is used for the black box function of the flight control to store flight data. The flight control can be used normally without this part.

• The USB debugging interface and RX0-TX0 are the same serial port, and only one of them can be connected. This serial port can only be used for parameter debugging and cannot be connected to GPS;
• The receiver has three types of wiring: SBUS/PPM/PWM, you can choose any one, SBUS is recommended;
• CH1/3/4/5 pins are multiplexed, so when the receiver is connected to CH1-8, PPM, serial port 1, SBUS, and LED light strip will not be available;
• Serial port 1 (TX1-RX1) can be connected to GPS, but at this time the receiver cannot be connected to the flight control through SBUS, so PPM can be used;
