T41-main board-V012: common questions

What microcontroller does the T41-main board-V012 use?

The T41-main board-V012 is built around the MASWS0179, from the AVR/Arduino family.

How big is the T41-main board-V012?

The T41-main board-V012 measures 100 × 100 mm, has 4 copper layers and is 1.6458 mm thick.

How many components are on the T41-main board-V012?

95 components, from 50 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 T41-main board-V012 design files?

From the DRWJSCHMIDT/T41 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 T41-main board-V012 design in my own project?

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

Can I test firmware for the T41-main board-V012 without the hardware?

Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug AVR/Arduino firmware against it before you order a PCB.
