Feature

●*Resolution: 72*40
●*Driver IC: SSD1306
●* Brightness: Supports 256 levels of adjustable brightness
●* Communication Interface: 4-wire SPI/IC, default SPI
●* Resistor SPI is removed and welded to ICC position The end of the R 5 is short-circuited by tin, and the dc and cs pins are ground up. The res pins are controlled by io to complete the reset, and the reset method first keeps the RES pin at a level of 20 ms, the RES pin operates at a high level to complete the reset operation and then OLED is initialized, so ic=SDA can communicate with iic
