Lab 8 Breadboard: common questions
What microcontroller does the Lab 8 Breadboard use?
The Lab 8 Breadboard is built around the ATTINY102-SSNR, from the AVR/Arduino family.
How big is the Lab 8 Breadboard PCB?
The Lab 8 Breadboard measures 167.6 × 114.3 mm, has 2 copper layers and is 1.6 mm thick.
How many components are on the Lab 8 Breadboard?
67 components, from 50 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 Lab 8 Breadboard design files?
From the MVaugn/ECSE_371_2024 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 Lab 8 Breadboard design in my own project?
The repository has no license, so all rights stay with MVaugn. Use it as a reference, and ask the author before reusing the design.
Can I test firmware for the Lab 8 Breadboard 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.
