2.42inch IIC OLED Module SKU:MC242GX

Product Picture

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
