The ESP32-P4 boards ESP-KVM runs on, side by side. Pick the ones you are choosing between; the address of this page keeps the choice, so it can be sent to someone. "Untested" means built from the vendor's schematic and not yet run by anyone. Green marks the best of the boards shown. The first row is the board's rating for a KVM, out of five.
