Key Features
A microcontroller-based circuit to drive the valves, mass flow controllers and other components of a multi-channel olfactometer.
- Works with Teensy 4.0
- Can communicate with a PC over USB/Serial
- Drives up to six 8-valve manifolds (i.e., up to 48 odor valves)
- Plus 8 more stand-alone connections for 3-way valves (for blank, timing, and other valves)
- 4 BNC connections to Teensy pins that have PWM and Analog Input capabilities
- Header with connections to 13 more Teensy pins
- Connections for up to 4 Sensirion SFC6000D mass flow controllers
- One QWIIC connector to easily incorporate of a wide range of I2C devices
- Optional On/Off switch
PCB Fabrication
The full fabrication design is included in the Gerber Zip File. You can upload this file to any PCB fabricator to get a quote and place an order. (The board does not have any special features, so the default settings for PCB manufacture are probably fine.) One relatively low-cost option for this board is the $33/board (3 board minimum) special at Advanced Circuits.
PCB Assembly
A full list of components is listed in the BOM (bill of materials) spreadsheet. Note that some of the components are options and can be left unpopulated if you don't plan to use them.

Questions
How big is the HMS Olfactometer PCB?
It measures 279.4 × 137.2 mm and has 2 copper layers, 1.6 mm thick.
What parts does the HMS Olfactometer use?
78 parts, built around the R-78B12-2.0, MCP23008-E/P, ULN2803A and 500SSP1S1M6QEA. 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 HMS Olfactometer KiCad files?
From the HMS-RIC/HMS-Olfactometer repository on GitHub, at the commit this page was made from: the board is PCB-v4-KiCAD/HMS Olfactometer.kicad_pcb and its schematic PCB-v4-KiCAD/HMS Olfactometer.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the HMS Olfactometer design in my own project?
Its repository publishes it under the MIT licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
