Other key parts include the ADG1606BRUZ and ADAFRUIT_QT_PY. By type, the board carries 4 connectors, 2 ICs and 1 module.
From the project
Custom PCB with SAMD21 QT PY controlling TWO ADG1606BRUZ 16 input muxes!
--> UPDATED design available: muxboardv5 <--
The SAMD21 QT PY can be programmed with the qtpysamd21-usbtmc.uf2 file (drag-n-drop) and has the same USBTMC commands that my Mux Board V1 had. Here is the list:
MUX1:EN 1 # enable MUX1, a zero will disable the mux
MUX1:SEL 1 # select S1 input, values 1 through 16 are valid
MUX1:EN? # this query returns the state of MUX1
