Weather station poc: common questions
What microcontroller does the Weather station poc use?
The Weather station poc is built around the STM32U5G9ZJT6Q, from the STM32 family.
How big is the Weather station poc PCB?
The Weather station poc measures 165 × 91.2 mm, has 4 copper layers and is 1.6062 mm thick.
How many components are on the Weather station poc?
141 components, from 59 distinct parts. The full bill of materials is listed on this page.
Where can I download the Weather station poc design files?
From the CruvixDev/weather-station-poc repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.
Can I use the Weather station poc design in my own project?
The repository has no license, so all rights stay with CruvixDev. Use it as a reference, and ask the author before reusing the design.
Can I test firmware for the Weather station poc 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.
