I'll be brief.
I want to make a single-rocket launch controller, with a 50m cablec dual line. I'll use a differential line. I'll put a i2c or an SPI I/O extender on the far-away part.
So I need dual line transceivers, like SN-75176, but for SPI or I2C. BUT I can't find anything like that. I've been goooogling, but with no result. And I don't want to put MCUs on both ends. Is there an IC like that, or I'm in a dead end? :roll:
