ALaMode v3: common questions
What microcontroller does the ALaMode v3 use?
The ALaMode v3 is built around the ATMEGA328-PU, from the AVR/Arduino family.
How big is the ALaMode v3 PCB?
The ALaMode v3 measures 85.1 × 55.9 mm and is 1.6002 mm thick.
How many components are on the ALaMode v3?
76 components, from 53 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 ALaMode v3 design files?
From the wyolum/Wyolum-old-archive repository on GitHub, which has the KiCad layout and the BOM; the links under Design files point to each one.
Can I use the ALaMode v3 design in my own project?
The repository has no license, so all rights stay with wyolum. Use it as a reference, and ask the author before reusing the design.
Can I test firmware for the ALaMode v3 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.
