Keyestudio CNC V0.9A board+3pcs 4988 Driver W/Heat Sink + USB cable for arduino CNC/laser engraving machine/writing robots GRBL

Build your own desktop fabrication tools with the Keyestudio CNC V0.9A Kit, featuring a GRBL-compatible mainboard, three A4988 stepper drivers with heatsinks, and a USB cable. This cost-effective bundle is perfect for South African makers, educators, and DIY enthusiasts looking to assemble their own CNC routers, laser engravers, or writing robots. It provides a reliable, easy-to-configure foundation for precise motion control in your workshop or classroom.

Versatile GRBL control board

The Keyestudio CNC V0.9A board is designed specifically for driving CNC machines, laser engravers, and writing robots. It features complete interfaces for external connections, making it highly cost-effective and suitable for both DIY projects and light factory applications.

High-performance stepper motor drivers

The three included A4988 DMOS microstepping drivers can operate bipolar stepper motors at up to 35V and 2A. They feature built-in overcurrent protection and a fixed off-time current regulator that automatically operates in slow or mixed-decay modes.

ATmega328p processing power

Powered by an onboard ATmega328p microprocessor, the control board operates on a 12V DC input voltage. It natively supports standard G-code file formats, making it compatible with popular open-source control software.

Flexible microstepping resolution

Achieve precise motion control with five selectable step modes, ranging from full-step down to 1/16-step resolution. These options allow you to balance torque and positional accuracy based on your machine's requirements.

Onboard protection and tuning

An adjustable potentiometer lets you fine-tune the maximum current output for higher step rates. The drivers also feature comprehensive safety systems, including overheat thermal shutdown, under-voltage lockout, and short-circuit protection.
