Lilygo T5-4.7 - ePaper Weather Station

E-Paper Weather Display — Case & Stand

A desk weather station. The 4.7" e-paper panel holds its image with the power off, so there is no glow, no fan, and nothing to distract you — it simply looks like a printed card that happens to be up to date.

What it shows

• Current conditions: temperature, "feels like", and a large weather icon

• 5-day forecast with daily highs and lows and expected rainfall

• Hourly outlook graph for the next 24 hours, with weather icons on the curve

• Detail grid: sunrise and sunset, UV index, humidity, pressure, air quality, wind speed and direction

• Indoor temperature and humidity from a sensor inside the case

• Status line: last refresh, WiFi signal, battery level

Weather comes from OpenWeatherMap. The display wakes on a schedule (30 minutes by default), fetches, redraws and goes back to sleep.

The print

Four parts, printed flat, no supports:

• Screen frame (x1), holds the panel, friction fit

• Base / stand (x1), houses the board, battery and sensor

• Button caps (x3), reach the board's side buttons

0.2mm, add supports on the Screen frame only, like shown here

Electronics

• LilyGo T5 4.7" ESP32-S3 e-paper board

• AHT20 temperature/humidity breakout

• 3.7V LiPo battery, JST-PH 1.25mm (1000mAh fits well)

• Thin hookup wire and heatshrink

The sensor needs four wires to the board's header. USB-C charges the battery and flashes the firmware.
