CNC Shield UNO R3 Board 4xA4988 Driver Kit With Heatsink For Arduino Engraver 3D Printer | Игрушки и хобби

    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. - 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.   - Uno 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   Click to download universal course   Shippimg List:   1 x Uno R3 Board 1 x CNC Shield Board 4 x A4988 Stepper Motor Driver 4 x Heat Sink 1 x USB Cable 1 x 40-Pin Row Needles
