1.2 Key Features​

  • 0.96" OLED: Self-illuminating display with high contrast and low power consumption, suitable for static text and simple graphics
  • 1.14" TFT LCD: IPS wide viewing angle with SPI high-speed refresh and 65K colors, suitable for colorful UI interfaces
  • 1.54" TFT LCD: Large square screen with 262K colors and normally black mode display, suitable for interactive applications

1.3 NE301 Application Scenarios​

In the NE301 sensor expansion board, the display serves as a local status indicator and human-machine interface, capable of displaying detection results, device status, and configuration information directly on the device without connecting to a phone or computer to view NE301's running status and AI detection results.
