About the A shift PCB

A shift is an open source AVR/Arduino PCB design by lycronisxd, published on GitHub. It is a 2-layer board measuring 80 × 56 mm, with 30 components from 25 distinct parts.

Its main chip is the ATMEGA32U4-A, from the AVR/Arduino family. By type, the board carries 17 connectors, 7 capacitors, 3 resistors, 1 IC, 1 crystal and 1 switch.

From the project

i want to build a h-pattern shifter because every option for one is expensive and doesn't feel good.

A shift design files

The KiCad project lives in the lycronisxd/a-shift repository on GitHub; these links point at the commit this page was built from.

A shift: common questions

What microcontroller does the A shift use?

The A shift is built around the ATMEGA32U4-A, from the AVR/Arduino family.

How big is the A shift PCB?

The A shift measures 80 × 56 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the A shift?

30 components, from 25 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 A shift design files?

From the lycronisxd/a-shift 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 A shift design in my own project?

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

Can I test firmware for the A shift 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.
