The CNC Shield V3 Control Kit contains:
- 1 x CNC shield v3
- 4 x A4988
- 4 x Heatsink
CNC Shield V3 Control Kit
First of all, it is a UNO Shield. Designed to fit the entire electronics needed for a CNC/3D Printer in one small package for low cost. CNC Shield V3 interfaces an Arduino UNO to simply connect stepper motors. Also, the modular design includes a plug-in steppers drivers and extruder control electronics on an Arduino UNO shield for easy service. Furthermore, it eases part replacement, upgrade-ability, and expansion.
A4988 Driver Control Kit
This driver board using Allegro’s A4988 micro stepping bipolar stepper motor driver features adjustable current limiting, overcurrent and also, over-temperature protection, and five different micro step resolutions (down to 1/16-step). Furthermore, It operates from 8 V to 35 V and can deliver up to approximately 1 A per phase without a heat sink or forced air flow (it is rated for 2 A per coil with sufficient additional cooling via heatsink).
