ESP32-Wall-Clock-PCB

ESP32 based 30cm Wall Mounted Clock. WiFi, NTP, SNMP, web interface, MicroUsb, Type-C, HG3613 Retrofit

Can be retrofitted into a HG3613 Case, or use standalone with the wall mounting on the pcb, or in a 3D Printed Case.

3D Printable Case not done yet...

this is still a work in progress.

PCB itself should be final, but the software is still being worked on.

e.g Code for the light sensitivity sensor to automaticly adjust the display intensity

RTC PCF8563T code.

OLED coding, etc....
