This document describes the features and characteristics of the BTHQ 42008VSS-01 LCD module, including a 20-character (5 x 8 dots) x 4 lines STN positive yellow transflective LCD character module, driving duty of 1/16 duty, 1/5 bias, 'SAMSUNG' KS0066UP-10BCC LCD controller and driver or equivalent, and yellow-green LED04 backlight.
This document provides a complete description of the BTHQ 42008VSS-01 LCD character module, including its 20‑character by 4‑line STN positive yellow‑transflective display and the Samsung KS0066UP‑10BCC controller. Mechanical data such as overall size, viewing area and weight are listed, together with the pin‑out and signal definitions for interfacing the module.
Key electrical parameters are given, including the 5 V logic supply range, LCD supply voltage, LED backlight forward voltage and current, as well as absolute maximum ratings and environmental operating limits. Timing diagrams for write and read modes illustrate the required signal sequencing.
