This high-speed 4x UART media box can control RS232 x4/RS485 x4 devices. The speed of the RS232 x4/RS485 x4 can get up to 921600 bps for each port.
Features:
- A DS18B20 1-Wire temperature sensor
- 8x GPIO-controlled LEDs
- One GPIO 5V Mini Fan control pin with ON/OFF control
- 2.0mm and 2.54mm pitch
- A real-time clock (RTC) function with a CR1220 battery socket
- 4x UART board power selection jumper that can select between Pi 4 or Micro USB
- 5V Mini Fan power selection jumper that can select between Pi 4 or Micro USB
- 24C32 HAT EEPROM (i2c-0) provided for future software updates
- Programmable 24C32 EEPROM (i2c-1)
- A 20x2 40 pin cable that connects the 4x UART board to the Pi 4
- The Pi Model 4B board can still use Bluetooth & Wi-Fi
Output:
- RS232 x4/RS485 x4 uses RJ45 output
- Can be upgraded to RS232 x8/RS485 x8
- Each port's baud rate can get up to 921600 bps
Performance:
- Instead of one FT4232HL chip for four ports, this device uses 4x FT232RL chips for four ports for the best performance
- Instead of external USB cables, this device uses 4x Pogo Pin to connect to a USB signal
- No soldering of the USB signal required
- Easy to use - insert the Pi 4 in the correct position within the metal box and tighten 4 screws
- Power regulator converting 5V from the Pi 4 to provide an individual 3.3V power for the 4x UART Board
Demo Software:
- GUI DC fan control & temperature detection Python program
- A micro switch on the board that can be programmed for controlling 'Shut Down', 'Reboot' and much more
