E-Ink Weather Station
March 2026 – Present
Goal
A custom 2-layer ESP32-WROOM-32 PCB that drives a Waveshare 4.2" e-paper display with live weather data pulled over WiFi. The board includes a complete power path from USB-C input through a TP4056 charger and AMS1117-3.3 regulator to a stable 3.3V MCU supply.
Status
This project is currently in progress. A full writeup with schematics, PCB layout, and the finished build will be added once the board is assembled and tested.
Coming soon.
