Advantech UNO-220 RS485 Gateway-Raspberry Pi 4The kit supports either stand mount or DIN rail mount. Advantech provides AdvRaspbian operating system for the kit. It’s an image based on Raspbian Buster 2019-09-26 with SSH server enabled, and drivers for Epson RX8010 RTC, TI TCA9554 IO extender, and the serial to RS-232/485 chip used in UNO-220 kit. Alternatively, you could build the image yourself, but somehow there are not any instructions to build the drivers directly after installing Raspberry Pi OS Lite/Desktop by yourself.
