Hi new member. 
Had the possibility to get an older video wall, 2.5x3.5 meters, so i jumped on it hoping the panels could be used for making something with a ESP32 and Smartmatrix, but unfortunately the drivers on the panels are MBI5041, and the connectors are not Hub75, but Hub54 - 26 Pins.
Has anyone had any luck with those and smartmatrix?
Regards
Ronni
