Overview
SmokeSensorConnector7 is an open-source printed circuit board by josdo, from the josdo/smesh repository on GitHub. It is a 2-layer board of 32 × 15.2 mm with 5 parts on 8 nets, routed with 45 tracks and 6 vias.
Its parts include 4 connectors and 1 capacitor. It belongs with the radio and wireless boards of this library.
README
README.mdWhat is SMesh?
SMesh is a sensor mesh network ("smesh") that performs long duration environmental sensing for sustainability research at Stanford.
A smesh node (or "snode") consists of a sensor payload plus a Meshtastic board that can relay readings using long range LoRa radio.
Usage
snode is a Python package that contains all dependencies and code to read from snodes.
Files are organized into three directories:
- One-off scripts go into
snode/scripts - Reusable code that scripts can import go into
snode/snode - Tests for reusable code go into
snode/tests
To run any Python code:
- Install Poetry by following https://python-poetry.org/docs/#installing-with-pipx
- Enter the package you're using, e.g.,
cd snode - Install the Python dependencies the code needs, i.e.,
poetry install - Run a Python script, i.e.,
poetry run python PATH/TO/SCRIPT.PY
Customizing Meshtastic firmware
Snodes run a stable version of Meshtastic firmware with small modifications.
To access this firmware:
- Clone the firmware fork, i.e.
git clone https://github.com/josdo/meshtastic-firmware.git - Follow https://meshtastic.org/docs/development/firmware/build/ to set up PlatformIO, a tool to build firmware from source.

Questions
How big is the SmokeSensorConnector7 PCB?
It measures 32 × 15.2 mm and has 2 copper layers, 1 mm thick.
What parts does the SmokeSensorConnector7 use?
5 parts. 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 SmokeSensorConnector7 KiCad files?
From the josdo/smesh repository on GitHub, at the commit this page was made from: the board is boards/smokeSensorConnector7.kicad_pcb and its schematic boards/smokeSensorConnector7.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the SmokeSensorConnector7 design in my own project?
Its repository states no licence, so its author keeps all rights: ask josdo before reusing the design.
