KINGPRINT CNC Shield V3.0 Expansion Board for Arduino with 4pcs A4988 Stepper Motor Driver with Heatsink kits for Arduino

CNC Shield Board: > Open source firmware that runs on an UNO for Arduino that turns G-code commands into stepper signals > Jumpers to set the Micro-Stepping for the stepper drivers. (Some drivers like the DRV8825 can do up to 1/32 micro-stepping) A4988 Stepper Motor Driver: > Automatic current decay mode detection / selection. > Internal UVLO. > Mixed with slow current decay modes. > Synchronous rectification for low power dissipation. > Crossover-current protection. > Thermal shutdown circuitry. > 3.3 and 5 V compatible logic supply. > Thermal shutdown circuitry. > Ground Fault Circuit. > Load short-circuit protection. > Of five optional step mode: full, 1/2, 1/4, 1/8 and 1/16. NOTICE: > powered can destroy the driver. (More generally, rewiring anything while it is powered is asking for trouble > Please note that this is an unassembled kit and Basic soldering skills are needed > At the moment only the DRV8825 drivers can handle up to 36V so please consider the operation voltage when powering the board Package Contents: 1 x CNC Shield Board 4 x A4988 Stepper Motor Driver(Green) 4 x Heat Sink Notice:There is no jumper.
