This 4K UART media box can control RS232 x2/RS485 x2 devices. There is a built-in 4K splitter for you to connect the standard HDMI cable between a TV and this media box. The speed of the RS232 x2/RS485 x2 can get up to 9600 bps for each port.
Features:
- 2x 4K HDMI splitters for 1 to 2 with HDMI signal input from the Pi 4B's HDMI 0/1
- 4x standard HDMI connectors that can connect up to 4 monitors (Pi 4B HDMI 0/1 that connect to two sets of 1 to 2 4K HDMI splitters)
- Both the Pi 4B audio output and USB-C power input are on the front panel side
- 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 4B or Micro USB
- 5V Mini Fan power selection jumper that can select between Pi 4B 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 4B
- The Pi Model 4B board can still use Bluetooth & Wi-Fi
- RS485 uses driver software to control the auto RTS
- Can choose between Black/Space Gray for the metal case
Output:
- RS232 x2 and RS485 x2 uses RJ45 output
- Each port's baud rate can get up to 9600 bps
Performance:
- Power regulator converting 5V from the Pi 4B to provide an individual 3.3V power for the 4x UART Board
Demo Software:
- A micro switch on the board that can be programmed for controlling 'Shut Down', 'Reboot' and much more
