Software dev board: common questions
What microcontroller does the Software dev board use?
The Software dev board is built around the STM32L152RET6, from the STM32 family.
How big is the Software dev board?
The Software dev board measures 83 × 53 mm, has 4 copper layers and is 1.6 mm thick.
How many components are on the Software dev board?
81 components, from 60 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 Software dev board design files?
From the awsmit07/Software_dev_board 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 Software dev board design in my own project?
The repository has no license, so all rights stay with awsmit07. Use it as a reference, and ask the author before reusing the design.
Can I test firmware for the Software dev board 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.
