High Speed 4x UART / 8x UART  - RS232 /RS485  

  with Raspberry Pi  4B

   

 

1. Provide RS232 x4 / RS485 x4   RJ45 output
2. Can upgrade to  RS232 x8 / RS485 x8
3. Each port Baud Rate can up to 921600
4. Use 4x FT232RL for each port to make sure each port got best performance.
    not use FT4232HL one chip to 4 port.
5. Use 4x Pogo Pin connect to USB signal, no need to use external USB cable.
    no soldering required, easy to use, just plug-in Pi4 with 4 screws.
6. On board DS18B20 1Wire Temperature sensor

8. 1 GPIO 5V Mini Fan control pin (ON/OFF control ) ( 2.0mm / 2.54mm pitch )
9. On board RTC function with CR1220 Battery socket
10. 4 UART  Board Power select jumper from Pi or Micro USB
11. 5V Mini Fan Power select jumper from Pi or Micro USB
12. Provide DC fan control & Temp detect demo python program GUI interface
13. It provides an individual 3.3V power for UART Board
14. Provide 24C32 HAT EEPROM (i2c-0) for future driver program update.
15. Provide 24C32 EEPROM (i2c-1) for future function use.
16. One software control Micro Switch for Program ( Shut Down , reboot....)
17. Use 20x2 40pin cable connect to Pi
18. PCB size 195mm x 85mm
19. Metal Box size 200mm x 125mm x 55mm
20. Metal Box with 80mm x80mm & 50mm x50mm fan screw hole
21. Raspberry Pi model 4B still can use on board Bluetooth & WiFi

 This port signal connect to on board USB Hub, can't use external device.

 

ls /dev

you will find ttyUSB0/ttyUSB1/ttyUSB2/ttyUSB3 in system

 

 can be upgrade to 8 UART (RS232 x8/RS485 x8)

 

 

   cutecom will detect 4 com port in system can be each to use 4 COM port

 

ttyUSB0/ttyUSB1/ttyUSB2/ttyUSB3 in system each port baud rate up to 921600

 

Provide DC fan demo program with Temperature detect and trigger Temperature setting
