ESP-KVM is free, open-source firmware that turns an ESP32-P4 board into an IP-KVM: another computer's screen, keyboard and mouse in your browser, from the BIOS up. The M5Stack Mini OLED Unit is an optional extra: a small screen on the box that shows its address and health. What it does → Try the demo →
A 0.42" 72x40 SSD1315 panel with a Grove cable. On the M5Stack Unit PoE-P4 it plugs in with nothing to solder and nothing to set.

The Grove port on the M5Stack Unit PoE-P4 is an I2C bus of its own, and the firmware for that board already knows its pins. Any other board can use it the same way: name the two pins as OLED SDA and OLED SCL under Settings → Display.
Twelve characters to a line and four lines under the heading, so it shows the address, the link, the picture's size and the health figures, one screen at a time.
