Is there any pins or interface to connect relay? #7

For TTGO Camera Plus module, is there any way to connect a relay ?

I have ordered one, on the way, looking at the explanations given the BME sensor can be turned off but not sure if the pins can be used for connecting or relay.

Or is there any way at all to connect a relay to this board?

There is a gif image at the bottom of my readme. It is set to recognize the face and light blue led. Use pcf8574 to expand the IO port. BME280 and camera use the same set of I2C, I2C port cannot be set to use it

Oh I see the GIF now. Is it possible to share picture on how you connected the LED to it?

Looking at the board input connectors, are the IO23 and IO18 pins functions as SDA and SCL? referred from the product picture: https://ae01.alicdn.com/kf/HTB1ssueLHrpK1RjSZTEq6AWAVXal.jpg
