CNC Expansion Board, Akozon CNC Shield Expansion Board + 4Pcs A4988 Stepper Motor Driver With Heatsink for Engraver 3D Printer Arduino Kits Engraving Machine by Amazon.co.uk
- • 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.
Description
A powerful combination of CNC Expansion Board and Akozon CN Shield expansion board, this is the perfect kit for engraving machines or 3D printer driver applications. With this set, you can easily create your own stepper motor driver shield and microstepping functionality with high accuracy and ease. This board provides a convenient interface for power sourcing, stepper motor connections, and LED lighting. Additionally, each of the CNC Expansion Board\'s soldered points and all soldering surfaces have been pre-treated to increase productivity.
A compact driver for quick implementation in any circuit or machine control system. With the added shielding of Akozon technology, your electronic designs are immune to external noise and field disturbances. 1 V digital resolution enables precise G-code communication, with additional current sourcing from any logic power supply with less than 65 mW per cm2 of 0.9-Ω resistive loading, A4988 motor drive in a complete microstep solution is provided for up to 35V, and microstepping for precision and power reduction up to a 0.05 kilogram package with exposed heat sink technology to ensure optimal efficiency, A Kozon shield can be disassembled into a single compact expansion board in your desired color that will meet specific 4 Pins and Akozon Stepper Drivers Color in any board type without damaging Akozon products. You may not require other stepper driver modifications. It is also suitable for any G code program that provides high accuracy, precise microsteps for a high quality result of your own production machine control or user interface system in a few minutes and complete functionality that has the advantage.
Each individual expansion board also includes LED light drivers for improved performance. With this combination of expansion board and shield technology, you can enjoy all these advantages without compromising any features. With these, Akozon provides you with the freedom to implement high precision machine control at an incredibly affordable price for professional production systems or the quality of control required for any small project you want to develop in your garage.
