ModuleV440: common questions

What microcontroller does the ModuleV440 use?

The ModuleV440 is built around the ATTINY841-SSU, from the AVR/Arduino family.

How big is the ModuleV440 PCB?

The ModuleV440 measures 30 × 61.4 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the ModuleV440?

42 components, from 27 distinct parts, with part numbers taken from the project's own BOM. The full bill of materials is listed on this page.

Where can I download the ModuleV440 design files?

From the chipsi/diyBMSv4 repository on GitHub, which has the KiCad layout, the schematic and the BOM; the links under Design files point to each one.

Can I use the ModuleV440 design in my own project?

It is published under CC-BY-NC-4.0, which limits how it may be reused; read the license before building on it.

Can I test firmware for the ModuleV440 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.
