Overview
Wemos mains dev is an open-source printed circuit board by chof747, from the chof747/wemos-mains-dev repository on GitHub, published under the CC0-1.0 licence. It is a 2-layer board of 74.2 × 46.5 mm with 15 parts on 21 nets, routed with 147 tracks and 5 vias.
It is built around the WEMOS D1 MINI. Its parts include 4 connectors, 2 capacitors, 2 resistors and 2 ICs. It belongs with the ESP8266 boards of this library.
Main components
1README
README.mdBoard to combine a Wemos D1 Mini with a mini power supply
This is a small board that can take a Wemos D1 Mini together with a 5V mini power supply to obtain a W-Lan microcontroller board with IO pins able to put e.g. in a switch box and power it directly from mains
It contains the following elements:
- WeMos D1 Mini (or any other microcontroller board that has the same pin configuration)
- A 600mA/5V (3W) power supply
- A 2x12 pinheader providing all GPIO Pins of the D1 mini in a suitable configuration
- Pull-Up Resistors for the SDA and SCL line
- Jumper Pins to select if the pullups should be used or not
- ByPass Capacitors for the 3V3 and GND lines in vicinity to the One-Wire and analog pin
- Screw Terminal to connect the board to mains
Features
The breakout of the pins is designed in a way that it can support HATs of a certain form factor. So far I have designed the following HATs which you can find here:
- RJ11 Socket HAT chof747/rj11-wemos-hat
Revision History:
- v1.0: Initial version (filed for fabrication: 19.04.2023)
- v1.1: Revision 1 with corrected orientation of power supply and reduced ground plane to avoid collision with high voltage (filed for fabrication: 17.7.2023; First Assembly 06.10.2023)

Questions
How big is the Wemos mains dev PCB?
It measures 74.2 × 46.5 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Wemos mains dev use?
15 parts, built around the WEMOS D1 MINI. 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 Wemos mains dev KiCad files?
From the chof747/wemos-mains-dev repository on GitHub, at the commit this page was made from: the board is wemos-mains-dev.kicad_pcb and its schematic wemos-mains-dev.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Wemos mains dev design in my own project?
Its repository publishes it under the CC0-1.0 licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
