Four Serial Ports RS485 and RS232 Stackable HAT for Raspberry Pi

Four Serial Ports RS485 and RS232 Stackable HAT for Raspberry PiOverview Four serial port HAT for Raspberry Pi with each port individually configurable as RS 232 or RS 485 via DIP switches. Uses the Raspberry Pi's native UART interfaces no additional software required, drivers are included in the Linux kernel. Stackable on top of any other HAT via an extra tall 220 connector. Four serial ports each independently configurable as RS 232 or RS 485 via DIP switch RS485 max 921,600 bps RS232 max 230,400 bps On board
