1.3-inch OLED expansion board with built-in SH1107 driver chip and using SPI and I2C interfaces for communication
Using four-wire SPI and I2C interfaces, good compatibility and high transmission speed
Provide complete supporting information manual (example program for Raspberry Pi/STM32)
Working current of 1.3inch OLED: about 29mA when fully on, 1.0mA when fully off
OLED has no backlight, and the display is self-illuminating. Only connect VCC and GND, the OLED will not light up. Program control is required to brighten the OLED
