PiKVM - Pi Zero 2 W

The official PiKVM is expensive so I decided take build my own & add some features in the process:

• Static MAC addresses to fix IP changes on reboot while using DHCP
• Small "USB dongle" form-factor with minimal connections
• Creates access point when network connection is lost for easy configuration
• Ethernet connection for wired networks
• E-ink display for showing network information
• Setup wireguard by adding a wg0.conf file to the boot partion to create a jumpbox

Hardware

• Pi Zero 2 W + SD Card
• Ethernet to SPI
• HDMI to CSI-2
• 2.13" E-Ink Display

Assembly

1. Cut the head off a USB cable & solder it to the debug pads on the back of the Pi; extend to the right (Opposite the SD card)
2. Connect HDMI/CSI-2 module via short ribbon cable (~40 mm); fold over and glue to back of board alighting with the SD card
3. Wire the Ethernet/SPI module onto SPI chanel 0
4. Connect E-Ink display via side pins to SPI channel 1

Install

1. Flash SD card with latest PiKVM image using the Raspberry Pi Imager
2. Edit /boot/config.txt to include:

dtoverlay=spi=on

3. Edit /boot/pikvm.txt to include your WiFi credentials for initial configuration:

FIRST_BOOT=1
WIFI_ESSID="wifi_name"
WIFI_PASSWD="wifi_pass"

4. Insert SD card into Pi, connect an HDMI cable to the PI HDMI output (not the added module), connect the USB port to power
5. After statup, open the IP address displayed in your browser & use admin/admin to login
6. Open the console, login as root & run the install script:

$ su -
