1602A Blue/ Yellow-Green
The LCD1602A character type liquid crystal display module is a dot matrix liquid crystal display module specifically for displaying letters, numerals, symbols, and the like. It is divided into 4-bit and 8-bit data transmission methods. Provides a 5×7 dot matrix + cursor display mode. A display data buffer DDRAM, a character generator CGROM, and a character generator CGRAM are provided, and CGRAM can be used to store font data of up to eight 5×8 dot matrix graphic characters defined by itself. Provides a wealth of command settings: clear display; cursor back to origin; display on / off; cursor on / off; display character flicker; cursor shift; display shift element. An internal power-on automatic reset circuit is provided. When the external power supply voltage exceeds +4.5V, the module is automatically initialized and the module is set to the default display working state.LCD1602A is an environmentally friendly liquid crystal display module.

Adapter board PCF8574:Due to different batches of manufacturers, the PCF8574 version on the board may also be different. Currently there are PCF8574T, PCF8574AT versions, the pin functions are the same, but the I2C device address is different. When the module is available, check the chip model first, and then modify the I2C ID number in the program.Default address : When shipped, A2~A0 are all left floating. The I2C address at this time is the default address in the table below. If you want to modify the address yourself, note that the address pad is floating and the short is 0.Product Features:The module uses the PCF8574, which enables most MCUs to implement remote I/O port expansion via two bidirectional buses (I2C). The device includes an 8-bit quasi-bidirectional port and an I2C bus interface. The PCF8574 has low current consumption and the port output latch has high current drive capability to directly drive the LED. It also has an interrupt line (INT open-drain output) that can be connected to the interrupt logic of the MCU. By sending an interrupt signal through INT, the remote I/O port can inform the MCU whether there is data input from the port without having to communicate via the I2C bus.Product parameters:-
Size: 41.mm (length) * 19mm (width) * 15.3mm (height)
