Overview
Neuron-1 is a universal 5-axis CNC controller based on Teensy 4.1. It runs grblHAL, the 32-bit firmware that brings features and performance to CNC machines that are out of reach for 8-bit controllers.
It is designed to be easy to install: inputs and outputs run through RJ45 connectors, which provide a secure, durable connection and make Neuron-1 plug-and-play with all expansions in the line.
Every connector also carries 5 or 24 V power, as in PoE: a single cable for both signal and power.
Features
- RJ45 connectors for fast, stable connections
- Plug-and-play with Neuron-1 expansions
- Inputs configurable as PNP or NPN, at 5 or 24 V
- Outputs selectable at 5 or 24 V
- 5/24 V power on every connector
- Compatible with grblHAL and ioSender
