Waveshare 3.6inch e-Paper HAT+ Schematic Replication

Overview

This project is a replication of the Waveshare 3.6inch e-Paper HAT+ schematics, originally documented in 3.6inch_e-Paper_HAT+_Schematics.pdf. The goal is to recreate the schematic faithfully in KiCad for learning, modification, or custom PCB development purposes.

The original hardware is a 600×400 pixel e-paper display HAT designed for the Raspberry Pi/ESP32, manufactured by Waveshare.

TODO

• Test on real hardware — validate the completed board against a physical microprocessor and e-paper display to confirm correct operation
• Review unnecessary components — some components from the original Waveshare driver circuit may not be needed depending on the target use case; evaluate what can be simplified or removed
