Using two i2c displays (pcb problem?)


 :o i'm absolutely confused one, i'm trying connect 2 displays same i2c bus displays have no pads address selection 0x3c/d.


bellow picture of , front of board

the 2 left screens identical, 1 on right type of screen isn't i2c ignore it.

so if have idea how can alter address of 1 of these fantastic?

you going have either use 2 buses or find diagram of display (or i2c adapter) can see how have set addresses.  may simple jumper somewhere - worst case hard coded (and can't modified).  without seeing diagram of display/adapter using, impossible tell how change it.
