Product Details

The MAX3232PMB1 peripheral module provides the necessary hardware to interface the MAX3232E true RS-232 transceiver to any system that utilizes Pmod™-compatible expansion ports configurable for UART communication. The IC has two receivers and two transmitters that are used to implement RS-232 data transmit and receive channels along with optional CTS and RTS handshaking. The RS-232 side input and output levels are true RS-232, achieved by incorporation of a dual internal charge pump.

Refer to the MAX3232E IC data sheet for detailed information regarding operation of the IC.
