Hi In my project, I have added before some built modules from User Contributed in EasyEda Std like TTL to RS485, 4 channel level shifter without any problem and now that I want to add a new module, any time that I search for a new module (PCF8574 module) or one that already is in my proyect (level shifter) , the response in User Contributed is Load fail. I wanted to know if it problem of EasyEda or where I have made a mistake.
