The ArcadeR USB aims to solve these problems plus introduces some extra features by simply providing a new PCB that fits inside the joystick with no modifications require and allows you to simply plug in the internal joystick and button cables.

* Recommended "Zero-Delay USB Encoder" cable. Other USB cables can be used, but you may need to add a JST XH connector or strip the cable and solder the 4 wires directly to the PCB.

Arcader usb: common questions

What microcontroller does the Arcader usb use?

The Arcader usb is built around the ATMEGA32U4RC-AU, from the AVR/Arduino family.

How big is the Arcader usb PCB?

The Arcader usb measures 82 × 30 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Arcader usb?

27 components, from 19 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 Arcader usb design files?

From the mbarszcz-pcb/arcader-usb repository on GitHub, which has the KiCad layout and the BOM; the links under Design files point to each one.

Can I use the Arcader usb design in my own project?

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

Can I test firmware for the Arcader usb 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.
