README
README.md#QPLFO v2.2 (also known as QPLFO v3)
This code runs on the STM32F030 version of the QPLFO, which is the factory-assembled version after March 2016. This code will not work on any kit versions of the QPLFO, nor any PCBs labeled version 1.x (green PCBs).
Note that one of the SWD programming pins is also used for the UI, so once the code has been flashed, it is difficult to re-flash it. The best technique I've found is to hit the reset button on the PCB at the right moment just before flashing.
This project was began using the [STM32F030x4 Application Template] (https://github.com/MrSpock/stm32f030x-gcc-template) from Martin Jurczuk, which is highly based on Mike Szczys [STM32F0-DISCOVERY template] (https://github.com/szczys/stm32f0-discovery-basic-template)

Questions
How big is the QPLFO v22 PCB?
It measures 59.1 × 110.7 mm and has 2 copper layers, 1.6 mm thick.
What parts does the QPLFO v22 use?
191 parts, built around the STM32F030K6T6, TL082, LD1117S33TR(MS) and PJ301M-12. 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 QPLFO v22 KiCad files?
From the 4ms/QPLFO-v22 repository on GitHub, at the commit this page was made from: the board is hardware/kicad v5/qplfo_v22.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the QPLFO v22 design in my own project?
Its repository states no licence, so its author keeps all rights: ask 4ms before reusing the design.
