It is incorporated into some versions of Pololu's [A-Star 32U4 Prime microcontroller boards](https://core-electronics.com.au/search/?q=a-star+32u4+prime) and Pololu's [Zumo 32U4](https://core-electronics.com.au/pololu-zumo-32u4-robot-kit-no-motors.html) and [3pi robots](https://core-electronics.com.au/pololu-3pi-robot.html). It uses the common HD44780 interface, so sample interface code is widely available for a variety of microcontrollers. This is the smallest package Pololu know of for this familiar interface. You can find sample HD44780 LCD interface code written for a variety of AVR microcontrollers as part of the Pololu AVR library. If you are using an Arduino board, you can get started with Arduino’s LiquidCrystal library. | [![](https://a.pololu-files.com/picture/0J9752.250.jpg?d3334b8c0994c53533e28d3aa62d6a1b)](https://a.pololu-files.com/picture/0J9752.1200.jpg?d3334b8c0994c53533e28d3aa62d6a1b) | |---| **Pinout** | Pin | Symbol | Function | |---|---|---| | 1 | Vss | ground (0 V) | | 2 | Vdd | 5 V logic supply voltage | | 3 | Vo | contrast adjustment | | 4 | RS | H/L register select signal | | 5 | R/W | H/L read/write signal | | 6 | E | H/L enable signal | | 7-14 | DB0 – DB7 | H/L data bus for 4- or 8-bit mode | **Note:** This item ships without pins (the pads are standard 0.1" spacing), connectors, or cables. **People often buy this product together with:** | [![0.100" (2.54 mm) Female Header: 1x5-Pin, Straight](https://a.pololu-files.com/picture/0J882.100.jpg?dda1afec386533fa148b2e2d4ccb8c43)](https://core-electronics.com.au/0-100-2-54-mm-female-header-1x5-pin-straight.html) | [0.100" (2.54 mm) Female Header: 1x5-Pin, Straight](https://core-electronics.com.au/0-100-2-54-mm-female-header-1x5-pin-straight.html) | |---|---| | [![Pololu Carrier with Sharp GP2Y0D810Z0F Digital Distance Sensor 10cm](https://a.pololu-files.com/picture/0J1178.100.jpg?1e233381650c535ce602e6dd72552262)](https://core-electronics.com.au/pololu-carrier-with-sharp-gp2y0d810z0f-digital-distance-sensor-10cm.html) | [Pololu Carrier with Sharp GP2Y0D810Z0F Digital Distance Sensor 10cm](https://core-electronics.com.au/pololu-carrier-with-sharp-gp2y0d810z0f-digital-distance-sensor-10cm.html) | |---|---| | [![Pololu Carrier with Sharp GP2Y0A60SZLF Analog Distance Sensor 10-150cm, 5V](https://a.pololu-files.com/picture/0J5782.100.jpg?d0dc29ca33bde495d7507411e2fa3a8d)](https://core-electronics.com.au/pololu-carrier-with-sharp-gp2y0a60szlf-analog-distance-sensor-10-150cm-5v.html) | [Pololu Carrier with Sharp GP2Y0A60SZLF Analog Distance Sensor 10-150cm, 5V](https://core-electronics.com.au/pololu-carrier-with-sharp-gp2y0a60szlf-analog-distance-sensor-10-150cm-5v.html) | |---|---| **Dimensions** | Size: | 40 x 35 x 7 mm | |---|---| | Viewing area: | 30 x 14 mm | | Dot size: | 0.5 x 0.5 mm | | Character size: | 2.78 x 4.49 mm | | Weight: | 12 g | **General specifications** | Minimum logic voltage: | 4.5 V | |---|---| | Maximum logic voltage: | 5.5 V | | Supply current: | 2 mA | **File downloads** - **Optrex DMC50448N-AAE-AD datasheet (109k pdf)** Pololu's 8×2 LCD is a generic equivalent of the Optrex DMC50448N-AAE-AD LCD, so the specifications and characteristics listed in Optrex’s datasheet apply. - **HD44780 interface datasheet (330k pdf)** This document details the HD44780 parallel interface that is an industry standard for dot-matrix LCDs. **Recommended links** - **[PololuHD44780 LCD library for Arduino](https://github.com/pololu/pololu-hd44780-arduino)** This is a C++ library for the Arduino IDE that allows you to control an LCD that uses the Hitachi HD44780 protocol. ## Images - [Product image 1](https://core-electronics.com.au/media/catalog/product/8/x/8x2_character_lcd_black_bezel__parallel_interface___pololu_356__00.jpg)
