A4988 Stepper Motor Driver A4988 Stepper Motor Driver Board is a breakout board for Allegro’s A4988 DMOS Micro stepping Driver with Translator and Overcurrent Protection please read the A4988 datasheet carefully before using this product. (At the moment only the DRV8825 drivers can handle up to 36V so please consider the operation voltage when powering the board.) Please note that this is an unassembled kit and Basic soldering skills are needed. Stepper Motors can be connected with 4 pin molex connectors or soldered in place. (Some drivers like the DRV8825 can do up to 1/32 micro-stepping ) Compact design. (Open source firmware that runs on an UNO for Arduino that turns G-code commands into stepper signals) PWM Spindle and direction pins 4-Axis support (X, Y, Z, A-Can duplicate X,Y,Z or do a full 4th axis with custom firmware using pins D12 and D13) 2 x End stops for each axis (6 in total) Coolant enable Uses removable A4988 or DRV8825 compatible stepper drivers Jumpers to set the Micro-Stepping for the stepper drivers. Features CNC Shield Board Latest CNC Shield Version 3.0 for Arduino. This shield simply sticks on top of your Arduino board and can control up to 4 stepper motors. Perfect for engravers, laser cutters, CNC machines and 3D printers.

Starting from the basics of electronics to more complex projects, the kit will help you control the physical world with sensors and actuators. Type: No battery version This is an upgraded version UNO R3 starter kit with more components You'll learn through building several creative projects. Specifications: Changed the USB chip, improve the download speed and stability of WIN7/WIN8 Microcontroller Atmel ATmega328 Operating Voltage (logic level): 5V Input Voltage (recommended): 7V ~ 12V Input Voltage (limits): 6V ~ 20 V Digital I/O Pins: 14 (of which 6 provide PWM output) Analog Input Pins: 8 DC Current per I/O Pin: 40mA Flash Memory: 32KB (ATmega328) (of which 2 KB used by bootloader) SRAM: 2KB (ATmega328) EEPROM: 1KB (ATmega328) Clock Speed: 16MHz Package includes: 1 x ATmega328P Arduino Compatible Nano V3 with USB cable 1 x NANO Shield Expansion Board Getting started with Arduino products So in the DC power connector provide external power supply to ensure the stability of equipment operation. Nano USB interface supply current is actually only 50MA, to bring high-current devices, such as the steering, is obviously insufficient. Increasing the DC power supply interface. Lead out the I2C interface of mainboard for convenient connection. Lead out all digital IO port and analog IO port, each one with standard positive and negative power interface. Description: This Nano Mult-Function expansion board is designed specially for Arduino Nano, solving the problem of confusing wiring when a variety of sensors connected.
