Practice1: common questions

What microcontroller does the Practice1 use?

The Practice1 is built around the ATTINY85-20PU, from the AVR/Arduino family.

How big is the Practice1 PCB?

The Practice1 measures 37.4 × 21 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Practice1?

11 components, from 10 distinct parts. The full bill of materials is listed on this page.

Where can I download the Practice1 design files?

From the m3llo0n/stat-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 Practice1 design in my own project?

The repository has no license, so all rights stay with m3llo0n. Use it as a reference, and ask the author before reusing the design.

Can I test firmware for the Practice1 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.
