SPARK Pyrotechnic Testing Board: common questions

What microcontroller does the SPARK Pyrotechnic Testing Board use?

The SPARK Pyrotechnic Testing Board is built around the Teensy4.1_bare, from the NXP family.

How big is the SPARK Pyrotechnic Testing Board?

The SPARK Pyrotechnic Testing Board measures 100 × 80 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the SPARK Pyrotechnic Testing Board?

70 components, from 22 distinct parts. The full bill of materials is listed on this page.

Where can I download the SPARK Pyrotechnic Testing Board design files?

From the ISSUIUC/ISS-PCB repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.

Can I use the SPARK Pyrotechnic Testing Board design in my own project?

The repository has no license, so all rights stay with ISSUIUC. Use it as a reference, and ask the author before reusing the design.

Can I test firmware for the SPARK Pyrotechnic Testing Board 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.
