![]() The stepper drivers are current limiting and will overheat if they are not connected. WARNING: Do not power up the board with stepper drivers installed if they are not connected to stepper motors. IMPORTANT: None of the components should be powered while installing or configuring. We recommend the Pololu DRV8825 driver carrier boards to complete this CNC Board. ![]() The board plugs directly into the Raspberry Pi General Purpose Input/Output pins, with the micro-controller and Raspberry Pi communicating via serial. The RPI CNC Board combines a real-time CNC controller(Micro-controller running GRBL) with a powerful credit card size computer(Raspberry Pi).īy combining the two systems we have created an eco-system where the Raspberry Pi provides benefits like: Processing power, connectivity(IOT) and a well supported community. Please see installation, configuration, and quick start guide below. This kit is powered by Raspberry Pi CNC board from Protoneer. 1 x Aluminum Heatsink for Raspberry Pi B+/2/3 (2-Pack).1 x Pre-configured Raspberry Pi CNC User Interface SD Card (Class 10 16GB SanDisk).1 x Female DC Power adapter – 2.1mm jack to screw terminal block.3 x DRV8825 Stepper Motor Driver Carrier, High Current.3 x Stepper Motor – NEMA 23 – 125 oz.in (200 steps/rev).
