YAMADAmain ver2.0: common questions
What microcontroller does the YAMADAmain ver2.0 use?
The YAMADAmain ver2.0 is built around the 4.7k, from the STM32 family.
How big is the YAMADAmain ver2.0 PCB?
The YAMADAmain ver2.0 measures 50 × 50 mm, has 2 copper layers and is 1.6 mm thick.
How many components are on the YAMADAmain ver2.0?
69 components, from 45 distinct parts. The full bill of materials is listed on this page.
Where can I download the YAMADAmain ver2.0 design files?
From the boiled-mackerel/NHK2024 repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.
Can I use the YAMADAmain ver2.0 design in my own project?
The repository has no license, so all rights stay with boiled-mackerel. Use it as a reference, and ask the author before reusing the design.
Can I test firmware for the YAMADAmain ver2.0 without the hardware?
Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug STM32 firmware against it before you order a PCB.
