Additional Details

The SO-194S-WS-SD-T utilizes a standard interface for communication with a microcontroller or other control system. The specific interface details (e.g., parallel or serial) should be confirmed with the device's datasheet. The module requires a power supply voltage typically in the range of 3.3V to 5V. The operating temperature range is typically between -20°C and +70°C, but should be confirmed with the datasheet. The display contrast can be adjusted using an external potentiometer or through software control, depending on the specific implementation. This LCD module is designed for indoor use and may not be suitable for direct sunlight applications without additional filtering or backlighting adjustments. The module's dimensions are typically around 80mm x 36mm x 13mm (check datasheet for exact values). Proper handling and electrostatic discharge (ESD) precautions are essential to prevent damage to the LCD module.
