GeeekPi 5PCS IIC I2C TWI SPI Serial Interface Board Module Port PCF8574 Expansion Board for LCD1602 LCD2004 Display

#ad
GeeekPi #ad - The default address is 0x27. The pcf8574t io expansion board features allowing the use of multi module connected to the I2C bus at the same time by connecting the pinheader and connector.

Package includes:5 x pcf8574t lcd driver board;technology support: https://wiki. 52pi. Com/index. Php/pcf8574t_lcd_driver_board_SKU:_D-0006. There is a small potentiometer onboard, which can adjust the backlight of LCD1602 or LCD2004, and a jumper cap to control the switch of the LED light. Up to 8 pcf8574t io expansion board can be connected to the I2C-bus, providing up to 64 I/O ports. The pcf8574t io expansion board is used as remote 8-bit i/o expander for i2c-bus; The device address can be modified by short-circuiting A0/A1/A2. The default address can be detected by the program.

1602 LCD 2004 20x4 i2c LCD Display Adapter IIC//TWI/SPI/I2C Serial Interface Module Shield for Arduino UNO R3 MEGA2560 2 Pcs

#ad
Ardest #ad - It saves from having to wire up and uses many gpio pins. 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.

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. The i2c module can drive 2 and 4 line LCD displays for Arduino. Works fine with the 2004 lcd display as well. 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. 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.
