| Apr 19, 2021 at 15:33 | comment | added | user130616 | I would do a search for multiple serial port hat for Raspberry Pi These hats come in up to eight ports (maybe more since I was involved in serial comms). Often they are using the SC16IS752 chip in I2C mode (SPI possible) for two ports and extra I/O pins | |
