Product description: 2 channel RS232 SP3232EEN transceiver module for Raspberry Pi Pico, UART - RS232 - Waveshare 19979
A module based on the SP3232EEN chip allowingthe Raspberry Pi Pico to communicate with devices using anRS232interface. The overlay allows to convert fromUART to RS232 and from RS232 to UARTand is equipped with 2 RS232 channels in form of ARK screw connectors and male pins. There are also LED's on the board indicating power and activity of both channels.
Product compatible withRaspberry Pi Pico
The manufacturer provides aproduct wiki pagewhich contains information about the module's pinouts and a detailed user guide.
