ODAmain ver2.0 design files

The KiCad project lives in the boiled-mackerel/NHK2024 repository on GitHub; these links point at the commit this page was built from.

ODAmain ver2.0: common questions

What microcontroller does the ODAmain ver2.0 use?

The ODAmain ver2.0 is built around the stm32_f446re, from the STM32 family.

How big is the ODAmain ver2.0 PCB?

The ODAmain ver2.0 measures 100 × 50 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the ODAmain ver2.0?

79 components, from 50 distinct parts. The full bill of materials is listed on this page.

Where can I download the ODAmain 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 ODAmain 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 ODAmain 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.
