I am starting a design that needs to run on a very unregulated power supply. Arcade systems for those that are interested. Voltage can vary quite a bit, so it would be good if the microcontroller could survive 5.4v or more. Since PJRC does not provide this directly, is it correct to use the Vin (MAX) of the onboard voltage regulator instead? If so, am I reading this right to say:
Teensy 3.2/3.5/3.6, LP38691 regulator, Vin 10.0v MAX
TeensyLC, integrated regulator, Vin 6.0v MAX
Teensy 4.0/4.1, TLV75733P regulator, Vin 5.5v MAX
This would be very unfortunate for the 4.x, but surprisingly robust for the 3.x. (So, of course 3.x chips are in short supply right now)
