Smart-Battery: common questions

What microcontroller does the Smart-Battery use?

The Smart-Battery is built around the ATMEGA328P-AU, from the AVR/Arduino family.

How big is the Smart-Battery PCB?

The Smart-Battery measures 28 × 10 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Smart-Battery?

66 components, from 48 distinct parts. The full bill of materials is listed on this page.

Where can I download the Smart-Battery design files?

From the G-Deni/Smart-Battery repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.

Can I use the Smart-Battery design in my own project?

The repository has no license, so all rights stay with G-Deni. Use it as a reference, and ask the author before reusing the design.

Can I test firmware for the Smart-Battery 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.
