Datasheet

Evaluates: MAX13485E/MAX13486E
Detailed Description of Hardware
The MAX13485E EV kit provides a proven layout for the
MAX13485E. On-board pads are included for adding
external fail-safe resistors. JU2 can be used to monitor
the A and B lines with a differential probe. A terminal
block is also included to easily connect a cable to the EV
kit board.
An electrical grid with vias and GND vias are present on
the board to enable prototyping.
