樹莓派高速UART閘道器(4x RS232/ 4x RS485)

商品特性

1. 1.  Build-in 4x RS232/ 4x RS485  ports with RJ45 jacks
   2.  The Baud Rate of each port can speed up to 921600 bps
   3.  Use one FT232RL for one port to get best performance. not use one FT4232HL for all 4 ports.
   4.  Use 4x Pogo Pin connect to one of RPi USB ports for signal communication, which located on the left-down corner of RPi USB ports, so not necessary to use extra USB cable/dongle to connect each other. Also no soldering required, easy to use. But this port has been occupied, don’t use it any more. If need, RPi still have 3 USB ports remain can be used.
   5.  On board DS18B20 1Wire Temperature sensor
   6.  Build-in 8 LEDs can be controlled via RPi GPIO
   7.  1 GPIO Mini Fan control pin (ON/OFF control ) ( 2.0mm / 2.54mm pitch )
   8.  On board RTC function with CR1220 battery socket
   9.  Power can be selected from RPi or Micro USB on board via jumper
   10.  Mini Fan Power also can be selected from RPi or Micro USB on board via jumper.
   11.  Provide DC fan control & Temp detect demo program with Python GUI interface
   12.  Built-in an individual 3.3V power for UART Board
   13.  Built-in 24C32 HAT EEPROM (i2c-0) for future driver program update.
   14.  Built-in 24C32 EEPROM (i2c-1) for future function use.
   15.  Use 20×2 40pin cable connect to RPi
   16.  Board size 195mm x 85mm
   17.  Metal case size: 200mm x 125mm x 55mm
   18.  Metal case reserved holes of size 80mm x 80mm and 50mm x 50mm for install fan
   19.  The Bluetooth & WiFi of RPi 4B are still available.
