LiFePO4-Fuel-Gauge: common questions
What microcontroller does the LiFePO4-Fuel-Gauge use?
The LiFePO4-Fuel-Gauge is built around the STM32L431CBT6, from the STM32 family.
How many components are on the LiFePO4-Fuel-Gauge?
138 components, from 39 distinct parts. The full bill of materials is listed on this page.
Where can I download the LiFePO4-Fuel-Gauge design files?
From the 20stefan05/LiFePO4-Fuel-Gauge repository on GitHub, which has a netlist; the links under Design files point to each one.
Can I use the LiFePO4-Fuel-Gauge design in my own project?
The repository has no license, so all rights stay with 20stefan05. Use it as a reference, and ask the author before reusing the design.
Can I test firmware for the LiFePO4-Fuel-Gauge 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.
