About the Banime40 PCB

Banime40 is an open source AVR/Arduino PCB design by ChrisChrisLoLo, published on GitHub under the CC-BY-SA-4.0 license. It is a 2-layer board measuring 190.5 × 76.2 mm, with 88 components from 6 distinct parts.

Its main chip is the ProMicro, from the AVR/Arduino family. By type, the board carries 47 switches, 40 diodes and 1 IC.

It belongs with the keyboards designs in this gallery.

From the project

A 4x10 hotswap ortholinear keyboard that supports multiple configurations.

When ordering from PCBWay or the like, the standard print settings should be fine, though I do recommend the Lead free HASL surface finish, mostly out of concern for long term health. If you think having a leaded surface is fine, feel free to go with that option.

Banime40: common questions

What microcontroller does the Banime40 use?

The Banime40 is built around the ProMicro, from the AVR/Arduino family.

How big is the Banime40 PCB?

The Banime40 measures 190.5 × 76.2 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Banime40?

88 components, from 6 distinct parts. The full bill of materials is listed on this page.

Where can I download the Banime40 design files?

From the ChrisChrisLoLo/banime40 repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.

Can I use the Banime40 design in my own project?

Yes, under the terms of its CC-BY-SA-4.0 license, which ChrisChrisLoLo chose for the repository.

Can I test firmware for the Banime40 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.
