This LCD has space for display with 2 lines of 16 characters. The display has white text on a blue background and uses the HD44780 'parallel interface' chipset and works on 5V. When you connect this module directly to the arduino, connect a resistor of 2K ohm to the contrast pin and 100 ohm to the backlight pin. Instead of the 2K contrast resistor, you can of course also connect a potentiometer to adjust the contrast. With the LCD interface module the module can easily be controlled via the I2C protocol: [product display] 10118 [/ product display] https://elecena.pl/product/27738301/opencircuit-16x2-characters-lcd-module-blue-5v 2025-01-22 https://elecena.pl/product/27738301/opencircuit-16x2-characters-lcd-module-blue-5v 2025-01-25 https://elecena.pl/product/27738301/opencircuit-16x2-characters-lcd-module-blue-5v 2025-01-30 https://elecena.pl/product/27738301/opencircuit-16x2-characters-lcd-module-blue-5v 2025-02-03 https://elecena.pl/product/27738301/opencircuit-16x2-characters-lcd-module-blue-5v 2025-02-06 https://elecena.pl/product/27738301/opencircuit-16x2-characters-lcd-module-blue-5v 2025-02-07 https://elecena.pl/product/27738301/opencircuit-16x2-characters-lcd-module-blue-5v 2025-03-19 https://elecena.pl/product/27738301/opencircuit-16x2-characters-lcd-module-blue-5v 2025-03-22 https://elecena.pl/product/27738301/opencircuit-16x2-characters-lcd-module-blue-5v 2025-04-20 https://elecena.pl/product/27738301/opencircuit-16x2-characters-lcd-module-blue-5v 2025-05-29 https://elecena.pl/product/27738301/opencircuit-16x2-characters-lcd-module-blue-5v 2025-11-18 https://elecena.pl/product/27738301/opencircuit-16x2-characters-lcd-module-blue-5v 2025-11-21 https://elecena.pl/product/27738301/opencircuit-16x2-characters-lcd-module-blue-5v 2026-02-23 https://elecena.pl/product/27738301/opencircuit-16x2-characters-lcd-module-blue-5v 2026-02-25 https://elecena.pl/product/27738301/opencircuit-16x2-characters-lcd-module-blue-5v 2026-04-14
