So, I’m starting to play with 485 and just noticed that:
a) The 485 gadgeteer module schematic shows it having 1 line buffer (U1).
b) But the image shows it having 2 line buffers (U1 and U2)
Which one is right: Schematic or picture?
What is the purpose of the buffer if the MAX13487 has a state machine to auto switch between RX/TX?
