Overview
Ng2040-controller is an open-source printed circuit board by partlyhuman, from the partlyhuman/ng2040 repository on GitHub, published under the BSD-2-Clause licence. It is a 2-layer board of 75 × 28 mm with 24 parts on 29 nets, routed with 162 tracks and 30 vias.
It is built around the MIC5205-3.0YM5. Its parts include 9 connectors, 4 capacitors, 2 resistors, 2 ICs and 2 switches. It belongs with the RP2040 boards of this library.

A cute DIY RP2040+2.4GHz wireless controller for Neo Geo
This is a wireless joystick and receiver for Neo Geo consoles that I designed to meet these requirments:
- Super compact joystick (6.5"x4.5" / 17x12cm)
- Super compact receiver (extends 1.5" / 4cm out from port)
- 3D printable
- Can use cheap Sanwa clones or the real thing
- No (less than 1 frame) of lag
- 2.4GHz radio, no pairing nonsense
- Long battery life with deep sleep
- USB-C rechargeable battery
- PCB using JST for tidy button wiring
It uses the ubiquitous RP2040 (specifically, the Waveshare RP2040 Tiny) and Nordic nRF24L01 radios.
Status
The project is ready for production, but there is a compatibility issue:
The DB15 connectors used are standard depth and work perfectly with supergun setups. However, to use with Neo Geo AES consoles and their extra-deep DB15 ports, a pigtail is required. There are AES specific designs in this repository that can be built using hand-soldered pins and a 3d-printed shroud, but I was never really happy with them, so they're not part of the "official" offering here - feel free to try them out if you so desire, of course.
The joystick design continues on as a BTLE joystick, which can pair with a Neo Geo BlueRetro dongle, any other console with BlueRetro, or your PC! See my ESP.Ra.Dio project.
Build instructions
Contact me for purchasing pre-built joysticks, or a build guide will be added to the wiki shortly.

Questions
How big is the Ng2040-controller PCB?
It measures 75 × 28 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Ng2040-controller use?
24 parts, built around the MIC5205-3.0YM5. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.
Where can I download the Ng2040-controller KiCad files?
From the partlyhuman/ng2040 repository on GitHub, at the commit this page was made from: the board is pcb/ng2040-controller/ng2040-controller.kicad_pcb and its schematic pcb/ng2040-controller/ng2040-controller.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Ng2040-controller design in my own project?
Its repository publishes it under the BSD-2-Clause licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
