I found this neat little board for under 3$.
It seems to have everything one could need for small projects as a perfect super-replacement for 8266.
Inbuild serial, onbord led, 3,3 or 5 V input, very small and enough pins.
Unfortunatly I cannot get it to wakeup from sleep with any rtc-pin.
My code works with a ESP32 devboard perfectly well.
Any ideas?
Regards and nice sunday
