A PCB for leoclees 7segment RGB clock
7seg clock is an open-source printed circuit board by Duckle29, from the Duckle29/7seg-clock-pcb repository on GitHub, published under the MIT licence. It is a 2-layer board of 26.3 × 31.5 mm with 12 parts on 7 nets, routed with 79 tracks and 4 vias.
It is built around the WEMOS D1 MINI and BSS138. Its parts include 4 resistors, 2 transistors, 2 connectors and 1 capacitor. It belongs with the lEDs and displays boards and the ESP8266 boards of this library.
This board has been made to work with this 7 segment clock. It uses 2 mosfets as level-shifters instead of the levelshifter chip originally used. It also incorporates the barrel-jack into the PCB

IAQ Board is a DIY (Do-It-Yourself) device for measuring internal air quality
It measures 26.3 × 31.5 mm and has 2 copper layers, 1.6 mm thick.
12 parts, built around the WEMOS D1 MINI 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 Duckle29/7seg-clock-pcb repository on GitHub, at the commit this page was made from: the board is 7seg-clock.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Its repository publishes it under the MIT licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
