The serial 20x4 LCD module from Nex-Robotics can be controlled by I2C or standard serial port with TTL 5V level signals. This dramatically reduces the number of pins consumed by LCD while interfacing with a microcontroller. It uses only two lines (TX and RX) for communication with any device. A well defined and easy to use protocol ensures smooth and error free operation.

  • Do NOT connect RS232 level interface directly to the module. It will destroy the module and will make it non-operational.
  • For 20x4 LCD user will not be able to use the contrast pot. This facility is only available for 16x2 LCD's.
