Description

WF0154ATAAA4DSN0 is a TFT-LCD with a 1.54-inch diagonal square screen and a resolution of 240x240 pixels. This square LCD screen adopts an IPS panel, which has the advantages of higher contrast, a full black background when the display or pixel is off, and wider viewing angles of Left:80 / Right:80 / Up:80 / Down:80 degrees (typical), 900:1 contrast ratio (typical value), 380 nits brightness (typical value), and an anti-glare glass surface.

This module is built-in with ST7789T3-G4-1 driver IC that can communicate via SPI interfaces. The supply voltage of analog is from 2.4V to 3.3V, with a typical value of 2.8V. It can operate at the temperature range from -10℃ to +60℃, and its storage temperature range is from -20℃ to +70℃. This 1.54-inch display module is suited for wireless microphone system, coffee scale, personal, and pulse oximeters.
