Sch2header: common questions

What microcontroller does the Sch2header use?

The Sch2header is built around the ATtiny2313-20SU, from the AVR/Arduino family.

How big is the Sch2header PCB?

The Sch2header measures 21.7 × 10.5 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Sch2header?

5 components, from 5 distinct parts. The full bill of materials is listed on this page.

Where can I download the Sch2header design files?

From the DeshmukhMalhar/sch2header repository on GitHub, which has the KiCad layout; the links under Design files point to each one.

Can I use the Sch2header design in my own project?

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

Can I test firmware for the Sch2header 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.
