Metstat: common questions
What microcontroller does the Metstat use?
The Metstat is built around the STM32L4A6RGTx, from the STM32 family.
How big is the Metstat PCB?
The Metstat measures 48 × 48 mm, has 2 copper layers and is 1.6 mm thick.
How many components are on the Metstat?
33 components, from 17 distinct parts. The full bill of materials is listed on this page.
Where can I download the Metstat design files?
From the MRtecno98/metstat repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.
Can I use the Metstat design in my own project?
The repository has no license, so all rights stay with MRtecno98. Use it as a reference, and ask the author before reusing the design.
Can I test firmware for the Metstat 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.
