I29ctfX

matrix clock

Overview

Corrected the problem of ESP not being grounded in the original project, and corrected the problem of incorrect use of TYPE-C in the original project (the CC pin was used as D+D-). Push all components together. Reduce the size of the board and use jumpers to splice 2 PCBs to achieve 4 dot matrix screens to display large text.
