Voltage monitoring: common questions
What microcontroller does the Voltage monitoring use?
The Voltage monitoring is built around the STM32L476RGTx, from the STM32 family.
How big is the Voltage monitoring PCB?
The Voltage monitoring measures 53.5 × 39 mm, has 2 copper layers and is 1.6 mm thick.
How many components are on the Voltage monitoring?
44 components, from 25 distinct parts. The full bill of materials is listed on this page.
Where can I download the Voltage monitoring design files?
From the AaravD356/voltage-monitoring-PCB repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.
Can I use the Voltage monitoring design in my own project?
The repository has no license, so all rights stay with AaravD356. Use it as a reference, and ask the author before reusing the design.
Can I test firmware for the Voltage monitoring 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.
