Description

Handy device for I2C interfacing.If you have some 1602/2004 displays or similar and you don't want to have to use 6 to 12 pins on your Arduino or Raspberry Pi just to drive the display then these are just the ticket.
An excellent improvement and conversion for older LCDs, and saves a lot of pins on the Arduino.The I2C interface is a huge improvement, freeing up a lot of pins on the Arduino for additional functionality and including the contrast control and backlight enable/disable.
Compatible for 1602 lcd. Works fine with the 2004 LCD display as well. The I2C module can drive 2 and 4 line lcd displays for Arduino.
This little I2C interface module works great and only two signal connections are required plus one each for power and ground.Good circuits to reduce the number of connections between your MCU and the lcd.
If you already have a bunch of the 1602s but they use up a ridiculous number of pins on the Arduino, this LCD module really make interfacing to LCD text displays easy with an arduino. It saves from having to wire up and uses many gpio pins.

Features: Supply voltage needed: 5V Saves using up data ports on the Arduino The backlight and contrast is adjusted by potentiometer/trimmer Come with 2 IIC interface, which can be connected by Dupont Line or IIC dedicated cable Compatible for 1602 lcds 2004 lcds.This module can drive 2 and 4 line LCd for Arduino With this I2C interface module, you will be able to realize data display via only 2 wires. I2C Address: 0X20~0X27 (the original address isÂ 0X20,you can change it yourself) Description: As there is limited pin on Arduino controller,your project may be not able to use normal LCD shield after connected with a certain quantity of sensors or SD card. However, with this I2C LCD serial interface module, you will be able to realize data display via only 2 wires. The I2C expander is address-selectable (8 values),and it provides 7 I/O ports and one switch-control port (backlight for lcd). It attaches directly to the usual 2x and 4x lcd with a single controller (e.g., 4x20). The brain is a PCF8574T 8-bit I2C GPIO expander wired up for 4-bit communication with the LCD. This board is capable of reading and writing in 4-bit mode, and it also can toggle the backlight. The register layout is: D7, D6, D5, D4, BACKLIGHT (wired to V0), E (clock/enable), R/W (direction), RS (command/data mode) For writing to the LCD, data is read out of the interface on the falling edge of the ENABLE bit. This means that you have to send each frame twice, once with ENABLE high, and then once again with ENABLE low. Note:These come with header pins already attached, but you still need to solder the pins to the display itself. If your display already has pins soldered on then you either have to unsolder them from either the interface board or the display, or you have to use jumper wires Package included: 2 Pcs *IIC series interface modules
