樹莓派高速UART閘道器(4x RS232/ 4x RS485)
商品特性
-
- Build-in 4x RS232/ 4x RS485 ports with RJ45 jacks
- The Baud Rate of each port can speed up to 921600 bps
- Use one FT232RL for one port to get best performance. not use one FT4232HL for all 4 ports.
- 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.
- On board DS18B20 1Wire Temperature sensor
- Build-in 8 LEDs can be controlled via RPi GPIO
- 1 GPIO Mini Fan control pin (ON/OFF control ) ( 2.0mm / 2.54mm pitch )
- On board RTC function with CR1220 battery socket
- Power can be selected from RPi or Micro USB on board via jumper
- Mini Fan Power also can be selected from RPi or Micro USB on board via jumper.
- Provide DC fan control & Temp detect demo program with Python GUI interface
- Built-in an individual 3.3V power for UART Board
- Built-in 24C32 HAT EEPROM (i2c-0) for future driver program update.
- Built-in 24C32 EEPROM (i2c-1) for future function use.
- Use 20×2 40pin cable connect to RPi
- Board size 195mm x 85mm
- Metal case size: 200mm x 125mm x 55mm
- Metal case reserved holes of size 80mm x 80mm and 50mm x 50mm for install fan
- The Bluetooth & WiFi of RPi 4B are still available.
