Overview
STM32F042-board is an open-source printed circuit board by jedp, from the jedp/STM32F042-board repository on GitHub. It is a 4-layer board of 48.8 × 35.1 mm with 35 parts on 32 nets, routed with 331 tracks and 55 vias.
It is built around the USBLC6-2SC6 and BK0603HS330-T. Its parts include 11 capacitors, 5 resistors, 4 connectors, 3 ICs and 1 diode. It belongs with the STM32 boards of this library.

Dev board for the STM32F042.
Programming
I'm using the ST-Link on an ST Discovery board to program this.
These ST Header CN2 Pins should be connected to the corresponding pins on this dev board:
- Don't connect
- CLK
- GND
- DIO
- NRST
Leave pin 1 (target 3V3) unconnected. It seems to do no harm, but it won't work if connected.

Questions
How big is the STM32F042-board PCB?
It measures 48.8 × 35.1 mm and has 4 copper layers, 1.6 mm thick.
What parts does the STM32F042-board use?
35 parts, built around the USBLC6-2SC6 and BK0603HS330-T. 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 STM32F042-board KiCad files?
From the jedp/STM32F042-board repository on GitHub, at the commit this page was made from: the board is stm32f042_board.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the STM32F042-board design in my own project?
Its repository states no licence, so its author keeps all rights: ask jedp before reusing the design.
