CNC Shield V3 for 4 motors for 3D printer overlay for Arduino - controller

An expansion module designed for building 3D printers or CNC machines, compatible with Arduino. The kit contains four A4988 stepper motor drivers to control motor movement with a maximum current consumption of up to 2 A using the included heat sinks. The module operates with a supply voltage of 12 to 36 V, and the logic part of the module is supplied with 3 V to 5.5 V. The A4988 controller offers motor operation in five different modes: full step, 1/2, 1/4, 1/8 and 1/16 step. Each module is equipped with a potentiometer to adjust the maximum current consumption. The expansion board also has I2C and UART interfaces for easy connection of additional devices such as an LCD display. Specification:

* Power supply: 5 ÷ 12 V

* Operating voltage of logic signals: 5 V

* Motor supply voltage: 12V - 36V

* Fully GRBL compliant

* Compatible with Arduino Uno (also with other compatible boards)

* 4 controller cradles A4988, DRV8825
