The initial project was based on Teensy 3.5 board with MK64FX512 processor. Unfortunately, these Teensy 3.5 boards are no longer available. Paul from PJRC.com do not believe supply of chips for Teensy 3.x is likely to ever fully recover. These chips are made with 90 nm silicon process. Most of the world's semiconductor fabs now are focusing on 45 nm or smaller, leaving limited supply for older chips.
That's why I moved the project to Teensy 4.1 board and, at the same transition, added an external ADC chip and digitally controlled high voltage. Thanks to the x9 higher core benchmark of the 4.1 vs 3.5!
