Heck, they only have RS232 and no USB to communicate with.

But you can add USB, unsolder RS232 board and solder "1602 LCD USB Mini Drive Board" then it will work with USB. This photo is from testing the NanoPi NEO-LTS USB port with "stress --cpu 4", it showed this on a 4 line LCD. Have a configuration file to display this information on the LCD screen. Gave it 4 stars because it doesn't have a USB port, you need to add a 1602 driver board to it. - Raymond Day

Pros

This is a high-performance serial bus with bus rules and high-speed or low-speed device clocks required for multi-master systems. The I2C bus has only two bidirectional signal lines, the serial data line (SDA) and the serial clock line (SCL).

Cons
