GU180x32D-K610A4 is a Dot Graphic VFD Module produced by Noritake Itron. It has a power supply voltage range of 4.5-5.25V, a working current of -350mA and a maximum display area of 79.05x13.95mm. The brightness is 1000cd/m2.
The GU180x32D-K610A4 is a 180 × 32 high‑brightness dot‑matrix VFD module that operates from a single 5 V DC supply. It offers three ASCII fonts, asynchronous, SPI and parallel interfaces, and a wide temperature range of –40 °C to +85 °C. The module includes the VFD glass, drivers, microcontroller, character generation, interface logic and a patented transformer‑less DC/DC converter.
The manual details electrical and environmental specifications, describes the software command set, and explains how to configure the interface, use synchronous/asynchronous/parallel communication, control I/O ports, display text and graphics, define areas, use write modes, and create macros. It also covers reset timing, keyboard control, and troubleshooting information.
