Overview
Module is an open-source printed circuit board by steand, from the steand/WeatherStation repository on GitHub, published under the GPL-3.0 licence. It is a 2-layer board with 14 parts on 51 nets, routed with 52 tracks and 0 vias.
It is built around the 74LVC2G14GW, MIC5501-3.0YM5-TR and BAR43SFILM. Its parts include 6 connectors, 5 ICs, 2 resistors and 1 diode. It belongs with the home automation and IoT boards and the ESP32 boards of this library.

README
README.mdWetterstation
Version 0.1 (under construction, not stabil)
In diesem Projekt habe ich mir eine kleine Wetterstation gebaut. Meine Motivation war, dass es eigentlich nichts erschwingliches gibt was in die offenen Smart-Home (bei mir openHAB2) integrierbar ist.
Leistungsmerkmale:
- Windgeschwindigkeit
- Windrichtung
- Regenmenge
- Regensensor
- Temperatur
- Luftdruck
- Luftfeuchtigkeit
- Helligkeit
Zur Steuerung meine Markise benötige ich Alarme für Regen und Windgeschwindigkeit. Die Rolladen werden mit Hilfe der Helligkeitssensor gesteuert.
Für Windgeschwindigkeit, -richtung und Regenmenge dienen die Sensoren eine AOK5055. Regensensor ist ein "China Modul". Temperatur, Luftdruck und -feuchte basieren auf einem BME280, Helligkeit auf dem BH1750.
Die Microcontroller Basis ist ESP-WROOM-32u (u wegen der Antenne).
Als Stromversorung dient eine 18500/3000mAh Batterie die über ein Modul(TP4056) geladen wird. Der Lader wird über ein MPPT-Modul (China) von einem 5W/12V Solarpenel versorgt. Als SDK setze ich platformIO auf Basis von Atom ein. Für Schaltpläne und Platinenlayout (Entwicklerplatine) nutze ich KiCad.

Questions
What parts does the Module use?
14 parts, built around the 74LVC2G14GW, MIC5501-3.0YM5-TR and BAR43SFILM. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.
Where can I download the Module KiCad files?
From the steand/WeatherStation repository on GitHub, at the commit this page was made from: the board is doc/kicad/Module/Module.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Module design in my own project?
Its repository publishes it under the GPL-3.0 licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
