YAMADAmain correct: common questions

What microcontroller does the YAMADAmain correct use?

The YAMADAmain correct is built around the STM32F446RETx-stm32, from the STM32 family.

How big is the YAMADAmain correct PCB?

The YAMADAmain correct measures 50 × 50 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the YAMADAmain correct?

54 components, from 37 distinct parts. The full bill of materials is listed on this page.

Where can I download the YAMADAmain correct 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 correct 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 correct 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.
