Dev board 1: common questions
What microcontroller does the Dev board 1 use?
The Dev board 1 is built around the STM32F427ZGTx, from the STM32 family.
How big is the Dev board 1?
The Dev board 1 measures 91.5 × 93.5 mm, has 2 copper layers and is 1.6 mm thick.
How many components are on the Dev board 1?
76 components, from 19 distinct parts. The full bill of materials is listed on this page.
Where can I download the Dev board 1 design files?
From the Delete228/OpenCalc repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.
Can I use the Dev board 1 design in my own project?
The repository has no license, so all rights stay with Delete228. Use it as a reference, and ask the author before reusing the design.
Can I test firmware for the Dev board 1 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.
