The Seiko Instruments G242C is a monochrome dot matrix LCD module engineered for industrial measurement and embedded system applications. This 240 × 128 dot display delivers high contrast visibility across a 134 mm × 76 mm viewing area, with integrated controller electronics simplifying host processor interfacing. The module operates from a single 5 V supply, drawing 40–50 mA typical, and includes FL backlighting rated at 3.5 W maximum. Its compact 180 mm × 110 mm × 15.1 mm footprint and 280 g weight enable space-constrained installations without compromising readability or performance.
