Overview
Feinstaub is an open-source printed circuit board by str-dst, from the str-dst/feinstaub repository on GitHub, published under the CC-BY-SA-4.0 licence. It is a 2-layer board of 67.1 × 62.2 mm with 14 parts on 16 nets, routed with 303 tracks and 0 vias.
It is built around the ESP-12F and AMS1117-3.3. Its parts include 4 resistors, 3 ICs, 3 connectors, 1 capacitor and 1 switch. It belongs with the sensors and measurement boards and the ESP8266 boards of this library.

ESP-12F powered piggyback PCB for the SDS011 fine dust sensor
The board is designed to run with the luftdaten.info firmware and has a place for a BME280 sensor.

Assembly notes
The SDS011 module gets connected to the J2 pins on the main PCB.
Remember that TX and RX have to be connected in reverse on the module.
The ESP chip can be flashed by connecting an ISP flasher to the J1 pins.
To put the chip into flashing mode set the boot switch to on, plug in the power and then turn the switch back off.
The easiest method of flashing the chip is by using the AirRohr firmware updater
For the main power input a 5v / 0.5-1A power supply should be used.
DO NOT CONNECT BOTH THE MAIN POWER AND A USB FLASHER WITH POWER INPUT AT ONCE!!!
If you use a flashing device that has 3.3v power output on it's own the main power has to be left unconnected.

Questions
How big is the Feinstaub PCB?
It measures 67.1 × 62.2 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Feinstaub use?
14 parts, built around the ESP-12F and AMS1117-3.3. 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 Feinstaub KiCad files?
From the str-dst/feinstaub repository on GitHub, at the commit this page was made from: the board is feinstaub.kicad_pcb and its schematic feinstaub.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Feinstaub design in my own project?
Its repository publishes it under the CC-BY-SA-4.0 licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
