Microcontroller-Breakout-Board: common questions
What microcontroller does the Microcontroller-Breakout-Board use?
The Microcontroller-Breakout-Board is built around the ATtiny85-20P, from the AVR/Arduino family.
How big is the Microcontroller-Breakout-Board?
The Microcontroller-Breakout-Board measures 59.5 × 44.5 mm, has 2 copper layers and is 1.6 mm thick.
How many components are on the Microcontroller-Breakout-Board?
7 components, from 6 distinct parts. The full bill of materials is listed on this page.
Where can I download the Microcontroller-Breakout-Board design files?
From the Sia3136/Microcontroller-Breakout-Board repository on GitHub, which has the KiCad layout; the links under Design files point to each one.
Can I use the Microcontroller-Breakout-Board design in my own project?
The repository has no license, so all rights stay with Sia3136. Use it as a reference, and ask the author before reusing the design.
Can I test firmware for the Microcontroller-Breakout-Board 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.
