V 3.0 Khắc Cnc + tặng Bảng + A4988 Động Cơ Bước Trình Điều Khiển Cho UNO R3 Arduino-quốc tế

Engraver CNC Shield Board +Arduino R3 Board + 4 x A4988 Stepper Motor Driver (1)Engraver CNC Shield Board Version:3.0 Color:Red Size(L*W*H):68 x 53 x 18 mm Voltage:DC 12~36 V (At the moment only the DRV8825 drivers can handle up to 36V so please consider the operation voltage when powering the board.) Features: 1.Uses removable A4988 or DRV8825 compatible stepper drivers. 2.The extension board can be used for carving machine, 3 d printer driver expansion board 3.GRBL 0.8 compatible. (Open source firmware that runs on an Arduino UNO that turns G-code commands into stepper signals) 4.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) 5.Compact design. Stepper Motors can be connected with 4 pin molex connectors or soldered in place. 6.Please note that this is an unassembled kit and Basic soldering skills are needed. (2)A4988 Stepper Motor Driver Color:Red Size(L*W*H):20 x 15 x 10 mm Thermal shutdown circuitry:Yes Crossover-current protection:Yes Ground fault protection:Yes Load short-circuit protection:Yes Compatible logic supply: 3.3V and 5 V Five selectable step modes: full, 1/2, 1/4, 1/8 and 1/16 Features: 1.Mix with slow current decay modes. 2.Internal UVLO and Low RDS (On) Output. 3.Automatic current decay mode detection/selection. 4.Synchronous rectification for low power dissipation. 5.Warning: Connecting or disconnecting a stepper motor while the driver is powered can destroy the driver. (3)Arduino R3 Board MCU: ATmega328 Clock speed: 16 MHz USB interface: ATmega16U2 Operating voltage: 5 V I-I/O pin output current: 40 mA max 3.3 V output current: 150 mA max Digital I/O pins: 14 (including 6 with PWM capability) Analog input pins: 6 EEPROM: 1 kB Static RAM (SRAM): 2 kB Flash memory: 32 kB Size(L*W*H):68 x 53 x 10 mm Package Included: 1 x Arduino R3 Board 1 x Engraver CNC Shield Board 4 x A4988 Stepper Motor Driver 1 x 40-Pin Row Needles 1 x Cable Note: Manual measuring, please allow 1 ~ 3 cm error,thank you.
