Product Description

  • 2.42” OLED monochrome screen, equipped with three monochrome displays: white, yellow, and blue
  • 128x64 resolution, clear display effect, high contrast
  • Large viewing angle: greater than 160 ° (the screen with the largest viewing angle in the display screen)
  • Wide voltage power supply (3V~5V), compatible with 3.3V and 5V logic levels, without the need for level conversion chips
  • Adopting IIC bus communication, only 4 IO ports are needed to light up
  • Equipped with an iron frame, it can effectively protect the display screen
  • Ultra low power consumption (much lower than TFT display screen)
  • Provide rich example learning programs (ESP32/STM32/ Arduino/C51/CH32/RaspberryPi)
  • Provide low-level driver technical support, and update WIKI information online
  • Multiple tests for module aging can meet military level standards, supporting long-term stable work
