[Retired] LCD1602 I2C/SPI Module (Double-Protocol)

Description

The common charctic LCD need more than 6 pins for controlling. With the limited pin resources, for example, the arduino board, your project may be out of resources using normal LCD shield. Here we provide the IIC/SPI LCD module, you only need 2 lines (I2C)or 3 lines(SPI) to display the information.

• It’s easily switch in between the two modes.

IIC mode connect the CLK pin to Analog 5 (i2c SCL pin) and DAT to Analog 4 (i2c SDA pin). Connect the 5V and ground pins to respective power pins.

SPI mode connect the CLK pin to Digital 2 (SPI Clock pin) and D to Digital 3 (SPI DATA pin) and L to Digital 4 (SPI Latch pin). Connect the 5V and ground pins to respective power pins.
