#17163 One limitation I have found as using this vs. a ATmega is analog sample rate. Espressif on twitter said that you can only sample at 200Hz, vs. ATmega328 can do 200kHz, which rules it out for me to sample a microphone.

@CptanPanic HW is fast, but software needs processing time. probably 200 Hz is OK.
