KIT: common questions

What microcontroller does the KIT use?

The KIT is built around the ATtiny45-20P, from the AVR/Arduino family.

How big is the KIT PCB?

The KIT measures 87.8 × 52.1 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the KIT?

24 components, from 11 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 KIT design files?

From the George-Emad31/Pcb 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 KIT design in my own project?

The repository has no license, so all rights stay with George-Emad31. Use it as a reference, and ask the author before reusing the design.

Can I test firmware for the KIT 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.
