ATinyStompbox: common questions
What microcontroller does the ATinyStompbox use?
The ATinyStompbox is built around the ATTINY85-20SU, from the AVR/Arduino family.
How big is the ATinyStompbox PCB?
The ATinyStompbox measures 33.3 × 120 mm, has 2 copper layers and is 1.6 mm thick.
How many components are on the ATinyStompbox?
50 components, from 31 distinct parts. The full bill of materials is listed on this page.
Where can I download the ATinyStompbox design files?
From the 8BitMixtape/ATinyStomp repository on GitHub, which has the KiCad layout; the links under Design files point to each one.
Can I use the ATinyStompbox design in my own project?
The repository has no license, so all rights stay with 8BitMixtape. Use it as a reference, and ask the author before reusing the design.
Can I test firmware for the ATinyStompbox 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.
