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
