Overview
Emw board is an open-source printed circuit board by AriZuu, from the AriZuu/emw-board repository on GitHub, published under the CC-BY-4.0 licence. It is a 2-layer board of 49.5 × 48.3 mm with 38 parts on 58 nets, routed with 613 tracks and 64 vias.
It is built around the MCP1640-I/MC, EMW3165 and MAX604CSA+T, with the B3S-1000 and SD25-4R7-R among its other parts. Its parts include 8 capacitors, 8 connectors, 5 resistors, 4 diodes and 3 ICs. It belongs with the sensors and measurement boards of this library.

README
README.mdEMW3165 sensor board
Kicad stuff for EMW3165 based sensor board v2. This small board has:
- EMW3165 module
- Connector for 1-wire sensors
- SWD connector for programming
- Two alternative power supplies (solder only one):
- MCP1640 step-up converter, provides 3.3V from 2 AA batteries
- MAX604 LDO regulator, provides 3.3V from 3 AAA batteries or from console FTDI
I have written two firmware alternatives for board. First is emw-meter, which displays temperatures and house power usage. Second is emw-sensor, which uses 1-wire devices to measure temperature and send it to MQTT server.
This is Open Source Hardware, licensed under CC-BY 4.0. There are some notes about the board in my blog.

Questions
How big is the Emw board PCB?
It measures 49.5 × 48.3 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Emw board use?
38 parts, built around the MCP1640-I/MC, EMW3165, MAX604CSA+T and B3S-1000. 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 Emw board KiCad files?
From the AriZuu/emw-board repository on GitHub, at the commit this page was made from: the board is emw-board.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Emw board design in my own project?
Its repository publishes it under the CC-BY-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).
