Battry-Management-System: common questions

What microcontroller does the Battry-Management-System use?

The Battry-Management-System is built around the ATMEGA328P-PU, from the AVR/Arduino family.

How big is the Battry-Management-System PCB?

The Battry-Management-System measures 156.7 × 80.6 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Battry-Management-System?

143 components, from 41 distinct parts. The full bill of materials is listed on this page.

Where can I download the Battry-Management-System design files?

From the src94/Battry-Management-System repository on GitHub, which has the KiCad layout; the links under Design files point to each one.

Can I use the Battry-Management-System design in my own project?

Yes, under the terms of its GPL-3.0 license, which src94 chose for the repository.

Can I test firmware for the Battry-Management-System without the hardware?

Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug AVR/Arduino firmware against it before you order a PCB.
