CNC Shield V3 3D Printer Expansion Board+A4988 Driver+UNO R3

CNC Shield V3 3D Printer Expansion Board+A4988 Driver+UNO R3

CNC Shield V3 3D Printer Expansion Board+A4988 Driver+UNO R3 Feature: This expansion board as a driver expansion board, can be used for engraving machines, 3D printers. It is a total of four slots, can drive four A4988 stepper motor. Each road stepper motors only need two IO ports. In other words, six IO ports can be well managed three stepper motors. Very convenient to use. UNO for Arduino module IO port correspondence introduction. Package included: 1 x 3D Printer Expansion Board 1 x UNO R3 board 4 x A4988 driver IO corresponding pin: (For reference only, actural item is SKU066313..)
