1. Provide extra 4 UART TTL output `
4x UART TTL output TX,RX,GND,3V3,CTS,RTS
2. 2 set i2c signal out GND,5V,SDA,SCL for extend extra UART HAT
3. TTL UART1 support ESP8266 WiFi module socket
4. It provides an individual 3.3V power for UART & output port
5. Provide HAT EEPROM for future driver program update.
Provide other Linux OS support (without HAT EEPROM )(option)
6. Extension port for RS232/Rs485 module board
7. Raspberry Pi model 3B & Pi Zero W still can use on board Bluetooth & WiFi
Serial GUI Control Panel
Control up to 4 Serial Ports
1. Scan: Scan for available UART devices.
2. Launch cutecom together when starting Serial Port.
3. Port number in system
4. Baud Rate choose
5.6.7. UART Port Information: Port Address 0x48,0x49, 0x4c, 0x4d
Chip Address Location, Channel Number ( 1 / 2 ), TX and RX receive counter,
and Serial port Location /dev/pts/X
8. RS485 : Enable RS485 in this Port
9. Start : Start UART port
Also provided is a terminal command mode to activate serial ports through a terminal / ssh.
You can also activate a serial port on boot up with the provided software.
Commands for starting the serial ports via command line; ./Pi485 -a ADDR -c CHANNEL -b BAUD -s DEVPTS
ADDR = Address of Serial Port e.g. 0x48, 0x49, 0x4C, and 0x4D
CHANNEL = Channel of serial Port ( 1 / 2 )
BAUD = Baud Rate for the Serial Port
DEVPTS = PICOM Service Number ( Will direct the filename to /dev/picomX where X = your number )
For example, To start a serial port from 0x49, on channel 2 with 9600 Baud run the following; ./Pi485 -a 0x4c -c 2 -b 9600 -s 1
This will activate the serial port and then set /dev/picom1 to your serial port location /dev/pts/X
