Review: Display LS12864 - Arrivato con un giorno di anticipo. Scelto per la possibilità di collegarsi con Arduino mediante il protocollo SPI che semplifica notevolmente il cablaggio (solo 3 fili). Inizialmente ho avuto qualche difficoltà perchè nessuno sketch sembrava funzionare ma poi mi sono reso conto che tutto dipendeva dal trimmer VR1 deputato alla regolazione del contrasto. Una veloce messa a punto di questo trimmer e tutto é andato OK. Prodotto consigliato. ## Features - 1.12864 LCD Smart Display Screen can be used for copiers, fax machines, laser printers,3D Printer, industrial test equipment, networking equipment etc. - 2.Large screen, clear white characters with blue backlight - 3.Provides multi-function commands:Display clear,Return home,Display on/off,Cursor on/off,Display character blink,Cursor shift,Display shift,Vertical line scroll,reverse display - 4.Module can display letters, numbers, Chinese fonts and graphics, mixed display graphics and text,in addition, it can display 128 (column) × 64 (row) lattice.8 × 4 (16 × 16 dot matrix) Chinese characters. - 5.Provides three control interfaces: 8-bit microprocessor interface, 4-bit microprocessor interface, serial interface. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B07B3PK94F | | Brand | HALJIA | | Brand Name | HALJIA | | Compatible Devices | Printer | | Compatible devices | Printer | | Customer Reviews | 4.0 out of 5 stars 13 Reviews | | Finish Type | Glossy | | Finish type | Glossy | | Item Hardness | 9H | | Item hardness | 9H | | Manufacturer | HALJIA | | Material | Glass | | Model Name | LCD-Bildschirm 12864 | | Model Number | 1 | | Number of Items | 1 | | Screen Size | 93 Millimeters | | Screen Surface Description | Glossy | | UPC | 782123447756 | | Unit Count | 1.0 Count | | Unit count | 1.0 Count | ## Images ![5V 12864 LCD Display Module 128x64 Dots Graphic Characters Letter Matrix Blue Backlight Compatible with Arduino Copiers Fax Machines Printers 3D Printer - Image 1](https://m.media-amazon.com/images/I/71pd3EDa5HL.jpg) ## Customer Reviews ### ⭐⭐⭐⭐⭐ Johan Demeyere *by J***E on 30 December 2024* Ecran graphique pour Arduino ça change... ### ⭐⭐⭐⭐⭐ Display LS12864 *by N***A on 31 May 2020* Arrivato con un giorno di anticipo.

Hay que poner un potenciometro de 10K entre masa y 3.3V, y el cursor de este al pin 3, para poder dar contraste y que el interno actúe. Así con sólo 4 cables, más los de alimentación, funciona. Luego usar este código de ejemplo: #include #include #include #include U8G2_ST7920_128X64_1_SW_SPI u8g2(U8G2_R0, /* clock=*/ 13, /* data=*/ 11, /* CS=*/ 10, /* reset=*/ U8X8_PIN_NONE); void setup(void) { u8g2.begin(); u8g2.setContrast(255); // en mi modelo no hace nada u8g2.setPowerSave(1); // en mi modelo no hace nada } uint8_t m = 24; void loop(void) { char m_str[3]; strcpy(m_str, u8x8_u8toa(m, 2)); /* convert m to a string with two digits */ u8g2.firstPage(); do { u8g2.setFont(u8g2_font_logisoso62_tn); u8g2.drawStr(0,63,"9"); u8g2.drawStr(33,63,":"); u8g2.drawStr(50,63,m_str); } while ( u8g2.nextPage() ); delay(1000); m++; if ( m == 60 ) m = 0; } ## Frequently Bought Together - HALJIA 5V 12864 LCD Display Module 128x64 Dots Graphic Characters Letter Matrix Blue Backlight Compatible with Arduino Copiers Fax Machines Printers 3D Printer - ELEGOO 120pcs Multicolored Dupont Wire 40pin Male to Female, 40pin Male to Male, 40pin Female to Female Breadboard Jumper Ribbon Cables Kit Compatible with Arduino Projects - AZDelivery DS3231 RTC Real Time Clock I2C compatible with Arduino and Raspberry Pi including E-Book! --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.uy/products/541201404-5v-12864-lcd-display-module-128x64-dots-graphic-characters-letter](https://www.desertcart.uy/products/541201404-5v-12864-lcd-display-module-128x64-dots-graphic-characters-letter) --- *Product available on Desertcart Uruguay* *Store origin: UY* *Last updated: 2026-04-24*
