Sketch for Arduino Nano 3.0 (CH340 - China) and board STM32F103C8T6 (Blue Pill)
rtl8367c.ino: VLAN switch setup based on Realtek RTL8367C(S) chips. Used TP-Link TL-SG1005D rev.7 (RTL8367S) after remove EEPROM chip from board switch!

For ARDUINO AVR:
Remove EEPROM 24cXX on switch board!!!! Pin SDA - D6 (convertor 5v-to-3.3v pin SDA on EEPROM switch(pin 5)) Pin SCK - D5 (convertor 5v-to-3.3v pin SCK on EEPROM switch(pin 6)) Arduino Vin - get from power connector 12V 5V - get from Arduino 5V 3.3V - get from EEPROM pin 8 on switch board
For ARDUINO STM32:
No need Logic Level Convertor, use pin-to-pin conection. Remove EEPROM 24cXX on switch board!!!! Cut on the board STM32 the track from power USB!!!! 3.3V get from EEPROM pin 8 on switch board. GND get from EEPROM pin 1-4 on switch board.
Pin SDA - PB10 (to EEPROM pin 5 on switch board) Pin SCK - PB11 (to EEPROM pin 6 on switch board)
