CNC kit UNO R3 ATmega328P CH340G & Shield & 4X A4988 Drivers for Arduino

$19.99

Features: 100% brand new and high quality Main Changes from the older version: Add two rows of the holes for the pins. So it can be connected with normal Dubond line. Add 3 rows of the holes for wiring. Change the in-line package of ATMEGA328P to flat package. CH340G Replace ATmega16U2 Plug UNO development board, the driver will be automatically installed. select the board UNO inside the die. Select the COM port, this can be in my computer queries, just inside your uno port development board You'd better to choose for arduino own routine procedures, burn into the board V3 Engraver 3D Printer CNC Shield Expansion Board A4988 Driver for Arduino This expansion board can be used for engraving machines and 3D printers 4 stepper motor connection. Each connection can control one A4988 moter That means you can connect 4 stepper motors into this board Each road stepper motors only need two IO ports In other words, six IO ports can be well managed Connection Instruction When inserting the A4988 module, must be careful not to insert opposite Stepper motor wiring as follows:2A, 2B is a group (red, green), 1A, 1B is a group (blue, yellow) If you want to change direction, change the position of one group Example: 2A and 2B can mutually be exchanged A4988 StepStick Stepper Motor Driver Module Heat sink for 3D Printer Reprap A4988 surface mount QFN package (ES), the size of 5 mm x 5 mm nominal overall package height of 0.90 mm, and with exposed pad for enhanced thermal dissipation. The package is Pb (suffixes-T), with 100% matte tin leadframe plating. Product Summary: Low RDS (ON) outputs<,A0-A5/li> Automatic current decay mode detection / selection Internal UVLO Mixed with slow current decay modes Synchronous rectification for low power dissipation Crossover-current protection Thermal shutdown circuitry 3.3 and 5 V compatible logic supply Thermal shutdown circuitry Ground Fault Circuit Load short-circuit protection Of five optional step mode: full, 1/2, 1/4, 1/8 and 1/16 Note: PCB Colors May vary Package Includes: 1 x New UNO R3 ATmega328P CH340G USB Driver Board and USB Cable For Arduino DIY 1 x USB Cable 1 x V3 Engraver 3D Printer CNC Shield Expansion Board A4988 Driver for Arduino 4 x A4988 StepStick Stepper Motor Driver Module Heat sink for 3D Printer Reprap 4 x Mini Heat Sink
