The P4, the ESP32-C6 and 16 MB of flash under one shield, on a carrier with 100M Ethernet, a card slot, a 2x20 header and four USB-A sockets. Every pin the KVM touches is one already in use, and a C790 ribbon plugs straight in. The -A, -B and -C kits are the same board with a different screen in the box.
Wiring
- A jumper switches the OTG-HS between one Type-A socket and an internal hub. The KVM wants the socket.
- That socket drives its own 5 V, so the lead to the target is an A-to-A cable with the 5 V wire cut.
Built from the schematic, not yet run on one.
Its 40-pin header has the Raspberry Pi layout, with the capture chip's I2C bus on pins 3 and 5, so a "DS3231 for Pi" clock module should plug straight onto pins 1-9 (read from the vendor pinout, not tried on this board).
