5V power supply. Serial I2C control of LCD display using PCF8574. Backlight can be enabled or disabled via a jumper on the board. Contrast control via a potentiometer. Can have 8 modules on a single I2C bus (change address via solder jumpers)address, allowing.
The MAX485 TTL to RS485 Module converts standard TTL serial signals (UART) from microcontrollers into differential RS485 signals for long-distance, high-noise industrial communication. Featuring a low-power MAX485 chip, onboard 5.08mm screw terminals, and 5V operation, it allows seamless multipoint networking and Modbus RTU communication up to 1200 meters with Arduino, Raspberry Pi, and PLCs.
