Attiny48: common questions
What microcontroller does the Attiny48 use?
The Attiny48 is built around the ATtiny88-AU, from the AVR/Arduino family.
How big is the Attiny48 PCB?
The Attiny48 measures 20.3 × 19.3 mm, has 2 copper layers and is 1.6 mm thick.
How many components are on the Attiny48?
10 components, from 9 distinct parts. The full bill of materials is listed on this page.
Where can I download the Attiny48 design files?
From the joshnuss/attiny48 repository on GitHub, which has the KiCad layout; the links under Design files point to each one.
Can I use the Attiny48 design in my own project?
The repository has no license, so all rights stay with joshnuss. Use it as a reference, and ask the author before reusing the design.
Can I test firmware for the Attiny48 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.
