4 Pieces hd44780 1602 lcd display module dc 5v 16 x 2 character lcm blue backlight compatible with Raspberry pi stm32 DIY maker project Nanopi bpi tinker board electrical internet of things

Introduction:
As we all know, though LCD and some other displays greatly enrich the man-machine interaction, they share a common weakness. When they are connected to a controller, multiple IOs will be occupied of the controller which has no so many outer ports. Also it restricts other functions of the controller.

Therefore, LCD1602 with an I2C port is developed to solve the problem. It is also simple to handle. It has only 2 bidirectional data lines, a serial data line and a serial clock one.

How to wire:
GND-GND; VCC-VCC; SDA-A4; SCL-A5

Specification:
Voltage: 5V DC
LCD display type: characters
Module dimension: 80 x 35 x 11 mm

Data:
1602 standard 16-pin interface, including:
Pin 1: VSS is the ground power.
2 Feet: VDD then 5V positive power supply.
3 Feet: V0 LCD contrast adjustment end, then the positive power supply when the contrast is the weakest, the highest contrast when grounded power, the contrast is too high will have a “ghosting”, when applied by a 10K potentiometer to adjust the contrast.
4 Feet: RS for the register selection, high-level data register selection, low-level instruction register selection.
5 Feet: R/W for the read and write signal lines, high-level read operation, low-level write operation.
6th Foot: E end is enable end, when E end jumps from high level to low level, the liquid crystal module carries out the order.
7 – 14 Feet: D0 – D7 for the 8-bit bidirectional data lines.
15 Feet: the positive power supply backlight
16th Foot: backlight power negative

Packing includes:
4 x HD44780 1602 LCD display module
Easy to use: less I/O ports are occupied, only 4, VCC, GND, SDA (serial data line), SCL (serial clock line); Use the i2c protocol to reduce the occupation of I/O ports, making it easier to add to the project, and less wiring is more beautiful
Commonly applied in: internet of things, DIY project, home animation, smart building, maker’s DIY project
Suitable for: compatible with all current development boards, for Raspberry pi, Tinker board, Nanopi, Banana pi, stm32 and so on; With a potentiometer applied to adjust backlight (color: blue) and contrast; Power supply: 5v
