Got my key 2 days ago. Nice box. Pin-out side of info sheet is practically useless, doesn't photograph well for zooming in. First thing I noticed was no visual indication of life when plugged-in. Saw first indication of life from syslog seeing usb. I also noticed one of JP1's pins isn't seated all the way, so the jumper sits crooked. I'll fix that myself. Second thing was in "Get Started with ESP32" where 'git clone --recursive https://github.com/espressif/esp-idf.git -b 4.4.1' fails with 'fatal: Remote branch 4.4.1 not found in upstream origin'. Knowing I already had esp32 support in my Arduino IDE, just had to update it to upload a blink program successfully. Pin 33 is blinking a yellow LED, Pin 32 doesn't blink the other LED. Funny I'm still not seeing a power LED, must be a bad led on pin 32. Will play with the RP2040 after I decide what I'm going to do about reporting the power LED.
