Product Features

  • 【KeeYees UNO R3 Board】 KeeYees UNO R3 Board uses the same ATmega328 and ATMega16U2 as official Uno R3 and 100% compatible with the official version. It comes with free 1.5m USB cable for convenient connection.
  • 【CNC Expansion Board with Free 20pcs Jumpers】This is the latest version of the expansion board, which can be used for engraving machines and 3D printers. It can drive 4 A4988/DRV8825 stepper motors. The jumper caps are necessary for CNC setups. You do not need to purchase this part extra.
  • 【DRV8825 Stepper Motor Driver w/ Heat Sink】DRV8825 is upgrade of A4988! It is a must-have module for 3D printers, CNCs and engraving machines. The 4-layer PCB board has better heat dissipation performance. 
  • 【Mechanical Switch Endstop】It uses a 22AWG wire that can withstand a current of 2A and a voltage of 300V. Better quality than traditional copper wire. It can reach the insulation temperature of 80℃. It is not easy to break, and very convenient to plug and remove.
  • 【Reliable technical support】If you don’t have a CD drive, please visit our website( www.keeyees.com ) to get relevant information or can contact us on Amazon, we will send PDF Document to you.
