• Commonly used in: copiers, fax machines, laser printers, industrial test equipment, networking equipment such as routers and storage devices.
• Power supply: 5V; Size: 80 x 36 mm, mini size is easy to carry and store.
• Works with Arduino UNO R3 MEGA2560 Nano Due, Raspberry Pi, etc.

Pinout: 1602 standard 16-pin interface, including: Pin 1 VSS: ground power. Pin 2 VDD: 5V positive power supply Pin 3 V0: V0 is the contrast adjustment terminal of the liquid crystal display. The contrast is the weakest when the positive power is connected, and the contrast is the highest when the power is grounded. When the contrast is too high, it will produce "shadow". When in use, you can adjust the contrast through a 10K potentiometer. Pin 4 RS: RS is the register selection, the data register is selected at high level, and the instruction register is selected at low level. Pin 5 RW: R/W is the read and write signal line, read operation when high level, and write operation when low level. When RS and RW are both at low level, you can write commands or display addresses. When RS is at low level, RW is at high level. Busy signal can be read. When RS is at high level, RW is at low level. Data can be written. Pin 6 E: The E terminal is the enable terminal. When the E terminal changes from high level to low level, the liquid crystal module executes the command. Pin 7 ~ 14 D0 ~ D7: D0～D7 are 8-bit bidirectional data lines. Pin 15 A: Positive backlight power supply Pin 16 K: Negative backlight power supply Specification: Model: LCD 1602 16x2 LCM type: Characters Character Color: White Resolution: 16 Characters x 2 Lines Voltage: 5V DC Module dimension: 80mm x 36mm x 11mm Weight: 32 g Packing List: 3 x 5V 1602 Character LCD Display Module
