The WO1602M is a monochrome COG (Chip-On-Glass) LCD display module that features a 16 characters x 2 lines configuration. This module is designed with an outline dimension of 51.2 x 20.7 mm and a viewing area (VA) size of 40.0 x 10.0 mm. The compact size makes it suitable for various applications where space is a consideration.

One of the key components of this display module is the ST7032Ai driver, which is integrated for efficient control and operation. The communication interface for this module is I2C, offering ease of integration with other devices or microcontrollers.

The operational temperature range of the WO1602M is between -20℃ and +70℃, making it suitable for diverse environmental conditions. Additionally, it can be stored within a temperature range of -30℃ to +80℃. The logic supply voltage for the WO1602M ranges from 2.9V to 3.1V, with a typical value of 3V. This voltage range ensures reliable and stable performance during operation.

It's worth noting that the WO1602M serves as an alternative model for the WO1602I, particularly in situations where there may be IC shortages or longer lead times for the original model.
