    Works. I've read some overcomplicated about the display. I got it to work with U8g2lib. I used the following constructor line: U8G2_SSD1306_128X64_NONAME_F_HW_I2C u8g2(U8G2_R0, /* reset=*/ U8X8_PIN_NONE, /* clock=*/ 16, /* data=*/ 17); this has to be changed to the right pins so it becomes: U8G2_SSD1306_128X64_NONAME_F_HW_I2C u8g2(U8G2_R0, /* reset=*/ 16, /* clock=*/ 15, /* data=*/ 4); This got it working for me with the usual U8g2lib functions.

    Very good board, but has a few downfalls. You can’t turn off the board and charge the battery at the same time. Also hardware Serial 2: GPIO 16 and 17 don’t work while using the OLED, to solve this problem I used jumper wire so the OLED rst is connected to 3V, and cut the trace to GPIO 16. Other than that it’s a very good board for an even greater price!

    The screen is placed in such a way that the pinout diagram is reversed. Look at the labels for the pins and don't assume from the diagrams. Similar to the Heltic WiFi Kit. Other than that I haven't been able to use the oled screen. not sure yet how to get it working.
