The gShield (grblShield) is a hardware solution that enables Arduino boards to function as CNC motion controllers. It provides all the necessary stepper motor control circuitry to run grbl firmware on Arduino Uno/328p boards or TinyG2 on Arduino Due boards. ## Key Features - **Complete Hardware Solution** — Includes all stepper motor drivers, power management, and interface circuitry needed for CNC control - **grbl Compatibility** — Designed specifically to work with the popular grbl CNC motion control firmware - **TinyG2 Support** — Can also run TinyG2 motion control system on Arduino Due boards - **Voltage Selection** — v5 version includes power selection for 3.3V, 5V, or Arduino IOREF voltage - **Arduino Platform** — Compatible with Uno and other 328p-based Arduino boards ## Philosophy The gShield provides a complete, ready-to-use hardware solution that makes CNC motion control accessible to Arduino users without requiring complex circuit design.
