5V M5Stack Stepper Motor Driver Board For Arduino ESP32 GRBL 12C MEGA328P With Fan

Feature: 1. This module contains a MEGA328P, which is equivalent to Arduino U N O, runs the modified GRBL library (open source) uses I2C to communicate with the host CORE, and can send GCODE to GRBL through I2C. 2. The default I2C address is 0x70. In principle, a host can connect multiple STEPMOTOR modules. Users need to modify the address to compile and burn. 3. Using high quality DRV8825 module, the peak current can reach 1.5A. Package Included: 1 x 5V Fan Module For M5Stack Stepmotor Module
