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 Round LCD - GC9A01 is an optional extra: a small screen on the box that shows its address and health. What it does → Try the demo →
A 1.28" 240x240 round colour SPI LCD. The same status pages in colour, plus a hotspot QR code a phone camera can join from.
| Status | Run on hardware |
|---|---|
| Controller | GC9A01, GC9A01A |
| Size | 1.28" 240x240; the 1.5" GC9A01A modules work too |
| Wiring | SPI - SCLK, MOSI, CS, DC and RST to free GPIOs, plus 3V3 and GND |
| Setting | Settings → Display |
For example the Waveshare module. Wire its SPI pins to any free GPIOs and pick them in the console. Each build offers a set of pins known to work on that board, so you only change them if you wired it differently.
Settings → Pins draws the board's expansion header the way it is printed, with what holds each pin, so a free GPIO is easy to find.
In hotspot mode it shows the join code, and it draws the recovery button's ring, which need the room.
