SensornodeV1.2: common questions
What microcontroller does the SensornodeV1.2 use?
The SensornodeV1.2 is built around the STM32L431CCUx, from the STM32 family.
How big is the SensornodeV1.2 PCB?
The SensornodeV1.2 measures 53 × 36 mm, has 6 copper layers and is 1.6 mm thick.
How many components are on the SensornodeV1.2?
88 components, from 50 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 SensornodeV1.2 design files?
From the Pro-engineer616/pcb_projects_Alex 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 SensornodeV1.2 design in my own project?
The repository has no license, so all rights stay with Pro-engineer616. Use it as a reference, and ask the author before reusing the design.
Can I test firmware for the SensornodeV1.2 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.
