We have just released the 202Q Switch Matrix as open-source hardware.
The 202Q Switch Matrix is a device for digital control of multiple microwave latching switches, both at room temperature and at cryogenic temperatures. It is designed for a 1-unit (1U) size 15-inch rack enclosure, and allows for the fast and tunable control, using Ethernet or Serial communication.
We are releasing the 202Q Switch Matrix through the CERN-OHL-S v2 open-source hardware license. The documentation is available on our GitHub repository.
