The RS422/RS485 Shield allows you OpenMV Cam to transmit data to an RS422 device or get on a RS485 bus. The YA+ and ZD- are the RS485 bidirectional pins (or RS422 receiver pins) while A+ and B- are the RS422 transmitter pins. The shield seamlessly handles either RS422 or RS485 (you cannot, though, do both at the same time). The transceivers are connected to P4 (TX) and P5 (RX) on your OpenMV Cam. You can disconnect these pins, too, if you don't need them. Better yet! The shield features a wide voltage range 6-36V input, which is robust to reverse voltage and features robust transient surge protection. Use this input to power your OpenMV Cam from 12/24V power supplies without having to worry about damaging your camera. The wide range voltage supply outputs 5.4V on VIN via an OR'ing diode so that you can power your OpenMV Cam from multiple shields with OR'ing diodes (e.g. all of our dual header column shields). The shield also features a robust 0-5V ADC input (AIN) that outputs 0-3.3V to
