CNC Shield – 3D Printer Driver – Shield for Arduino

From the shop's description

Description of CNC Shield – 3D printer driver – Shield for Arduino Shield for Arduino, which allows you to build a 3D printer driver or other CNC equipment’s driver. Thanks to the four connectors for the motor driver, e.g. A4988, it facilitates the use of stepper motors. The board is compatible with G-code interpreter, GRBL. It has derived inputs and inputs of the movement direction of the steps for four drivers, inputs for end sensors END STOP and outputs of I2C bus and UART. The module is compatible with Arduino Uno and Mega- Arduino boards can be purchased separately. Attention! Shield is compatible with the Protoneer product – however, this is not an original product of this company. With the ability to connect up to 4 stepper motors and a GRBL interpreter, creating your own 3D printer has never been easier. Shield is assembled – requires no soldering. A motor driver, for example A4988, must be purchased separately. Detailed information can be found in the user manual.
