Compatible Hardware
Rabbit GRBL is designed to run on ESP32-based hardware platforms, offering high performance, flexibility, and multi-axis support. Choosing the correct hardware is important to ensure stable operation, proper I/O availability, and reliable CNC control.
This section provides guidance on compatible development boards and hardware platforms that can be used with Rabbit GRBL. While many ESP32 boards follow similar designs, not all variants are equally suitable for CNC applications, so careful selection is recommended.
Rabbit GRBL runs on the ESP32 platform. Espressif provides the ESP32 as a standalone chip, as a module, and as a complete development board. In most cases, the recommended option is to use an ESP32 development board, as it already includes USB connectivity, voltage regulation, and the required supporting components for easy programming and communication.
The image shows the ESP32-DevKitC-32D development board, a widely used ESP32-based module suitable for running Rabbit GRBL.
Commonly used and tested development boards include:
- ESP32 DevKit
- NodeMCU-32S
- DOIT ESP32 DEVKIT
- ESPduino 32
There are many ESP32 development board variations available on the market. While most follow the standard pinout, some versions may differ in GPIO availability, USB-to-Serial chips, or voltage regulator quality. It is recommended to verify the board specifications and ensure compatibility before use with Rabbit GRBL.
