Serie: common questions
What microcontroller does the Serie use?
The Serie is built around the STM32H723ZGT6, from the STM32 family.
How big is the Serie PCB?
The Serie measures 160 × 136 mm, has 6 copper layers and is 1.6114 mm thick.
How many components are on the Serie?
512 components, from 65 distinct parts. The full bill of materials is listed on this page.
Where can I download the Serie design files?
From the npgo22/Serie repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.
Can I use the Serie design in my own project?
The repository has no license, so all rights stay with npgo22. Use it as a reference, and ask the author before reusing the design.
Can I test firmware for the Serie 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.
