3D Printer CNC Driver Arduino NANO Expansion Board Shield Kit with A4988 Stepper Motor Drivers

A ready-to-go development kit for controlling 3-axis stepper motors, a 3D printer for instance. The board has a holder for Arduino NANO and 3 pcs of A4988 stepsticks. All you need is to assemble the board, upload a program to the Nano and connect power and the motors. The set includes: CNC shield V3 for 3 motors - 1 pc. Clone Nano V3 ATmega328P 16MHz CH340G + USB cable - 1 pc. Stepper motor controller - StepStick A4988 + heat sink - 3 pcs. CNC shield specification for 3 motors: 3-axis stepper motor controller Supply voltage: 7.5V ÷ 12V Compatible with Arduino Nano (also with other boards) 3 sockets for A4988, DRV8825 controllers 2 endstops for each axis (6 in total) supports X, Y, Z axes The I2C interface allows connection to an I2C LCD or other I2C module GRBL compatible Nano V3 Specification: Supply voltage: 5 ÷ 12 V I/O pin voltages: 5V Arduino® Nano bootloader installed Microcontroller: ATmega 328 Maximum clock frequency: 16 MHz SRAM memory: 2 kB Flash memory: 32 kB (4 kB reserved for bootloader) EEPROM memory: 1 kB I/O ports: 14 PWM outputs: 6 Number of analog inputs: 8 (A/D converter channels) Serial interfaces: UART, SPI, I2C External interrupts Connector: Mini USB type B Dimensions: 43 x 18 mm Goldpins soldered to the board A4988 stepstick stepper motor driver specification: Supply voltage: 8 ÷ 35 V Continuous current per motor coil: 2 A (active cooling) Continuous current per motor coil: 1.2 A (passive cooling) Resolution: 1, 1/2, 1/4, 1/8, 1/16 step Connecting and disconnecting the engine while the controller is on may damage the system.
