OLED display for A4

[tarajas]

Hi,

Is it possible to add an I2C OlED display to the A4 via using the 433MHz PINs? On 1.2.4 board I have those available...

Maybe I could add the display to the DIN plastic enclosure creating a cutout with a dremel and fixing the display with screws, so that some important info could be shown there...

P3 has looking the board from head on:
VCC ? ? GND
Where should the SDA and SCL be connected?

KC868-A4 no i2c extender on PCB. if you want to use I2C, if you not used RF sender pin and IR receiver pin. i think you can remove the components, use two pins for i2c SDA and SCL pins.

Thanks, okay. So basically I would need to also desolder SMD parts from the board?

just remove IR receiver, it's DIP part , not SMD part, easy to remove.

Thanks, okay. That I can do defintiely. So one of the I2C data pins will come from the removal of IR-R and the other from the P3 header?

I guess there are no screens that I could connect (even other than the oled1366) without adjustment right? So there is no easier way?

1. Yes
2. the easy way is use SSD1306 i2c display. another way is chose Nextion serial port display.
