Product Details

The MAX14830 evaluation kit (EV kit) provides a proven design to evaluate the MAX14830 quad-channel universal asynchronous receiver-transmitter (UART) IC. Each UART contains 128 words of receive and transmit first-in/first-out (FIFO) buffer that can be controlled through the SPI or I²C interface. Each of the four UARTs are selected through SPI or I²C in-band addressing.

Each of the four UARTs can interface with an IO-Link® master transceiver or an RS-485/RS-232 multiprotocol transceiver. The EV kit contains on-board IO-Link master transceivers, RS-485/RS-232 multiprotocol transceivers, and double-pole/double-throw (DPDT) switches are used to select between the IO link and RS-485/RS-232 transceivers.

The EV kit operates from a +3.3V and a +24V DC supply and requires 100mA of current from each supply. This EV kit requires a user-supplied SPI/I²C controller and software.

The EV kit comes with a MAX14830ETM+ installed.
