Product Description

UNO R3 Board:

NEW IMPROVEMENT: Clearly print on the female header connector, more precise and easier to use the wire.

The Uno now uses an ATMega16U2 instead of the ATMega8U2 chip. Faster transfer rates and more memory.

Control using ATMEL ATMEGA328P chip

100% compatible with the official version

We have always cared about the customer experience and improve the product function details.

CNC Shield Board:

Each road stepper motors only need two IO ports.

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.

Stepper motor wiring as follows: 2A, 2B is a group (red, green), 1A, 1B is a group (blue, yellow), if want to change direction, can be change the position of one group , for example 2A, 2B mutually exchanged.

PWM Spindle and direction pins. 4-Axis support. Runs on 12-36V DC.

DRV8825 Driver Module:

This DRV8825 Stepper Motor Driver Module is upgrade of A4988.

Simple step and direction control interface.

4-layer, 2 oz copper PCB for improved heat dissipation.

Six different step resolutions: full-step, half-step, 1/4-step, 1/8-step, 1/16-step, and 1/32-step.

Adjustable current control lets you set the maximum current output with a potentiometer, which lets you use voltages above your stepper motor's rated voltage to achieve higher step rates.

Package List:

1x UNO R3 Board

1x USB Cable

1x CNC Board

4x DRV8825 Driver

4x Heat Sink

1x Screwdriver
