Mini receiver

WavePhoenix

Open-source implementation of the Nintendo WaveBird receiver using Silicon Labs Wireless Gecko SoCs

Motivation

The WaveBird controller is, in my opinion, one of the best controllers ever made. It is wireless, has an insane battery life, and is very comfortable to hold. The WaveBird set a new standard for wireless controllers. It was the first major console controller to use radio frequency (RF) technology, providing a reliable, lag-free connection that didn't require line-of-sight, unlike infrared controllers.

Unfortunately, Nintendo stopped producing the WaveBird more than a decade ago, causing a dwindling supply of controllers and, especially, receivers. Given the decreasing supply of receivers and the increasing resale prices, I decided to design my own from scratch.

Features

The reference implementation of WavePhoenix includes the following features:

• Full compatibility with the original WaveBird controller
• One-button virtual pairing, like modern wireless devices
• Status LED to indicate pairing status and radio activity
• Over-the-air firmware updates via Bluetooth
• Open source hardware and firmware
• 3D printable case

Buying a WavePhoenix

Don't want to build your own? A number of vendors are now selling pre-assembled WavePhoenix receivers!

• Laser Bear Industries - US-based seller, custom enclosure and PCB by Greg
• Colester Productions - US-based seller, uses my original PCB and SadSnifit's fantastic case
• Various AliExpress sellers

Building a WavePhoenix

The bare minimum hardware needed to build a WavePhoenix is a EFR32BG22 radio module (such as the RF-BM-BG22C3), a GameCube controller connector, and 3 wires!

Since most people prefer a more streamlined solution, I designed a custom PCB and 3D-printable case called the Mini Receiver.

You can find detailed build instructions in the hardware/mini-receiver directory.

Firmware Components

The firmware for WavePhoenix is composed of the following components:

• libwavebird - my implementation of Nintendo's WaveBird protocol for Silicon Labs Gecko SoCs
• libjoybus - my implementation of the Joybus protocol used by N64 and GameCube controllers
• firmware/app - the main app firmware; a reference implementation of a WaveBird receiver
• firmware/bootloader - bootloader to provide over-the-air firmware updates via Bluetooth
