HMS-Olfactometer: common questions
What microcontroller does the HMS-Olfactometer use?
The HMS-Olfactometer is built around the Teensy4.0, from the NXP family.
How big is the HMS-Olfactometer PCB?
The HMS-Olfactometer measures 279.4 × 137.2 mm, has 2 copper layers and is 1.6 mm thick.
How many components are on the HMS-Olfactometer?
58 components, from 29 distinct parts, with part numbers taken from the project's own BOM. The full bill of materials is listed on this page.
Where can I download the HMS-Olfactometer design files?
From the HMS-RIC/HMS-Olfactometer repository on GitHub, which has the KiCad layout, the schematic and the BOM; the links under Design files point to each one.
Can I use the HMS-Olfactometer design in my own project?
Yes, under the terms of its MIT license, which HMS-RIC chose for the repository.
Can I test firmware for the HMS-Olfactometer without the hardware?
Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug NXP firmware against it before you order a PCB.
