4runner-Seat-Heat: common questions

What microcontroller does the 4runner-Seat-Heat use?

The 4runner-Seat-Heat is built around the Teensy3.2, from the NXP family.

How big is the 4runner-Seat-Heat PCB?

The 4runner-Seat-Heat measures 74.4 × 71.5 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the 4runner-Seat-Heat?

72 components, from 36 distinct parts. The full bill of materials is listed on this page.

Where can I download the 4runner-Seat-Heat design files?

From the alorman/4runner-Seat-Heat-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 4runner-Seat-Heat design in my own project?

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

Can I test firmware for the 4runner-Seat-Heat 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.
