## Description

CNC Expansion Board, Akozon CNC Shield Expansion Board + 4Pcs A4988 Stepper Motor Driver With Heatsink for Engraver 3D Printer Kits Engraving Machine

## Features

- The A4988 is a complete microstep motor driver with built-in converter for ease of use. The product can operate bipolar stepper motors in half-continuous, 1/8 and 1/16 modes, with output performance up to 35 V and ± 1 A. Internal circuit protection includes: thermal shutdown with hysteresis, undervoltage lockout (UVLO), and cross current protection. No special power sequencing is required.
- The A4988 includes a fixed off time current regulator that can operate in slow or mixed damping mode. The converter is the key to the ease of use of the A4988. As long as you enter a pulse in the "Step " input, you can drive the motor to produce microsteps. There is no need for phase sequence tables, high frequency control lines, or complex interface programming.
- In microstep mode, the A4988 hash control automatically selects the current decay mode (slow or mixed). Hybrid attenuation current control schemes can reduce audible motor noise, increase step accuracy, and reduce power consumption. An internal synchronous rectification control circuit is provided to improve power consumption during pulse width modulation (PWM) operation.
- This is a set of disassembled parts, and you need some basic welding skills to weld them together. Use removable A4988 compatible stepper driver Expansion board can be used for engraving machine or 3D printer driver Compact design, stepper motor can connect 4 pin connectors or be soldered Jumpers to set Micro-Stepping for stepper pilots.
- Compatible with GRBL 0.8. Open-source firmware running on UNO, converting G code command to stepping signal.PWM steering and steering pin, 4-shaft support (X, Y, Z, A - you can copy X, Y, Z or use pins D12 and D13 The A4988 is available in a surface-mounted QFN (ES) package with dimensions of 5mm × 5mm, a nominal total package height of 0.90mm, and an exposed heat sink to improve performance. thermal dissipation.
