From what I can see, it looks like an ssd1306 with a tiny screen. You should be able to use u8g2 examples with this initializer.

Code: Select all

#define OLED_SDA 5
#define OLED_SCL 6
#define OLED_RESET U8X8_PIN_NONE // not connected to gpio
U8G2_SSD1306_72X40_ER_F_HW_I2C(U8G2_R0, OLED_RESET, OLED_SCL, OLED_SDA);
