Maxim's MAXM22511 is an isolated RS-485/RS-422, full-duplex transceiver module that provides 2500 VRMS (60 s) of galvanic isolation between the cable-side (RS-485/RS-422 driver/receiver side) and the UART-side of the device. An integrated DC-DC powers the cable-side of the module. No external components are required.
The MAXM22511EVKIT# is a fully assembled and tested PCB that demonstrates the functionality of the MAXM22511 isolated RS-485/RS-422 transceiver module. This kit operates from a single 3.3 V, 330 mA power supply. Required equipment to operate this evaluation kit includes power supply, signal/function generator, and an oscilloscope.
