Introduction
The NaxGCC is a GameCube-style controller built on the PhobGCC.
Like the PhobGCC, the NaxGCC uses hall effect sensors instead of potentiometers for stick input. Additionally, it connects directly to the console via USB, by pretending to be a GCC adapter with 1 controller (itself) connected. This eliminates one additional layer of polling, and thus reduces perceived latency and improves input consistency. The NaxGCC also features a special "input consistency mode" that even further improves input consistency, beyond what is delivered by any other controller / adapter.

Key Aspects
Click on any of these to expand.
NaxGCC has all the important PhobGCC features.
The hardware of NaxGCC is directly forked from PhobGCC's, meaning it benefits from the same improvements over a "regular" GCC, most importantly the fact that it uses hall-effect sensors instead of potentiometers for reading your stick positions.
Furthermore, large parts of its firmware have also been taken from PhobGCC's firmware, such as the snapback filter, cardinal snapping, and notch remapping to name a few. If you're used to calibrating a PhobGCC, you will have no trouble here.
Provides both the lowest latency of any Switch controller, as well as the best input integrity.
Because the NaxGCC connects directly to the console via USB, it already outperforms any controller that has to go through an adapter in terms of input latency.
Further, the NaxGCC has a special "input consistency" mode (enabled by default), which ensures a input accuracy, compared to for any other controller (worse if there is an adapter in the mix, with the exception of the Lossless Adapter).
For details on how it works, have a look at the Input Consistency Modes.
Compatible with Phob hardware.
The NaxGCC firmware is compatible with regular Phob 2.0 boards (those using an RP2040 microcontroller), since it's originally forked from the PhobGCC project. This means that if you are willing and able to slightly modify your controller shell to allow a micro USB cable to connect to your Phob board during play, you can turn your existing PhobGCC into a NaxGCC at no extra cost!
