Actually, this is all worth it if we gain a 4th output pin. That is just awesome.
Don’t burst my bubble, I was just feeling fancy!!
So the buffer from the arendale cost 30% less than the one from the JP1.
I am seeing a pulldown and current protection on the esp32 pins. That makes me nervous for GPIO.0. Can we leave it without a pulldown so it boots and flashes right, then specify :pd in the firmware for that output pin. I am guessing that makes this a flaky output but if it is used for non-critical things who cares if it blips on for a bit, (like pin 26 already does).
The esp32 gpio.0 boots high, low signals flash mode (it is tied to the boot button that pulls it down when pressed).
