NodeMCU WiFi, possibly, pending wireless viability in a pulse-magnetic environment. If Wifi is impractal in the dwell of a time lens, then fiber optic solutions should work to get telemetry and control to and from the power-electronics that encircles the Field Array windings.
When trained upon a well made Field Array, the Perceptorium of the quasiArtifactualIntelligence will visually represent, while connected and trained to the datastream outputs of an operating Field Array, the texture and dynamic behavior, in near real time, of the atomic matter lattice of the metamaterial within the array**.
That goal requires a fast state machine. FPGA engineers unite!
