Just finished the PCB routing and design for the ES_01 E-ink watch!!! Squeezing an ESP32-S3, like 3 display drivers, and 3 sensors into a SINGLE-SIDED board was kinda ridiculous, but in the end I managed to successfully route every signal trace WITHOUT violating design rules!!!! Idek how i managed this in 4 layers as well 💀
