The basic functions of USB-C are supported, such as high-speed communication and charging functions. Then this design solves the problem of painless switching between one host and multiple devices, or one device and multiple hosts.
Core64 combines real core memory and LEDs in a unique interactive way. Core Memory is a magnetic memory technology from the 1960s and 1970s. The tip of the stylus has a magnet that interacts with the LED through Core Memory. In practice, users can think of it as a magnetic touch screen
The analyzer host computer directly uses Wireshark. The hardware is implemented using Cypress CY7C68013A MCU + Lattice LCMXO2 FPGA + Microchip USB3343 USB PHY

Driver for WS2812, SK6812 or similar LED strips controlled via Bluetooth LE. It supports RGB and WWA LEDs. The drive uses motion and light sensors so in automatic mode it can turn on the lights when it detects the presence of someone in the dark.
A simple USB switch so I can swap a keyboard or mouse between two computers.
It is operated by 4 single mechanical switches, 1 for each channel. Simple designs can be implemented.
PCB for clipping onto Guillemot MAXI Gamer 3D Voodoo graphics accelerator. The common memory size for these cards is 4 MB. With the help of PCB you can get Voodoo up to 8 MB.
