Maiana Blue 11.9.2: common questions
What microcontroller does the Maiana Blue 11.9.2 use?
The Maiana Blue 11.9.2 is built around the STM32L432KBUX, from the STM32 family.
How big is the Maiana Blue 11.9.2 PCB?
The Maiana Blue 11.9.2 measures 84 × 25 mm, has 4 copper layers and is 1.564 mm thick.
How many components are on the Maiana Blue 11.9.2?
110 components, from 87 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 Maiana Blue 11.9.2 design files?
From the Haimana/MAIANA_BLUE 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 Maiana Blue 11.9.2 design in my own project?
The repository has no license, so all rights stay with Haimana. Use it as a reference, and ask the author before reusing the design.
Can I test firmware for the Maiana Blue 11.9.2 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.
