Hi
This is not a question. I have noted a number of unanswered questions on the DAC voltage range of esp-32 devices.
The measured no-load output is as follows:
(Read in 2 columns)
Digital .... Voltage
0 ________ 0.080
32 ______ 0.452
128 ____ 1.578
224 ____ 2.692
255 ____ 3.053
On the same dev board, the no load digital output voltages are:
Lo 0.08
