mathiasrabe/YAWS_PCBYet Another Weather Station
YAWS PCB is an open-source printed circuit board by mathiasrabe, from the mathiasrabe/YAWS_PCB repository on GitHub. It is a 2-layer board of 120 × 40 mm with 34 parts on 39 nets, routed with 259 tracks and 13 vias.
It is built around the ATTINY85-20SU, ESP-12F and TP4056, with the BSS138 and IRLML6344TRPBF among its other parts. Its parts include 14 resistors, 6 capacitors, 6 connectors, 4 ICs and 3 transistors. It belongs with the home automation and IoT boards and the ESP8266 and AVR (ATmega, ATtiny) boards of this library.
This is the PCB of my small IOT weather station. The weatherstation consists of the following parts:

It measures 120 × 40 mm and has 2 copper layers, 1.6 mm thick.
34 parts, built around the ATTINY85-20SU, ESP-12F, TP4056 and BSS138. 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.
From the mathiasrabe/YAWS_PCB repository on GitHub, at the commit this page was made from: the board is YAWS_PCB.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Its repository states no licence, so its author keeps all rights: ask mathiasrabe before reusing the design.
