MainboardTEST: common questions
What microcontroller does the MainboardTEST use?
The MainboardTEST is built around the TEENSY4.0, from the NXP family.
How big is the MainboardTEST PCB?
The MainboardTEST measures 125.7 × 140.3 mm, has 10 copper layers and is 1.6 mm thick.
How many components are on the MainboardTEST?
178 components, from 68 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 MainboardTEST design files?
From the annegautham/IEEE_TechnicalProgram_2026 repository on GitHub, which has the KiCad layout and the BOM; the links under Design files point to each one.
Can I use the MainboardTEST design in my own project?
The repository has no license, so all rights stay with annegautham. Use it as a reference, and ask the author before reusing the design.
Can I test firmware for the MainboardTEST 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.
