MODULE ET-MINI SMCC-547
ET-MINI SMCC-547
Module ET-MINI SMCC-547 which is STEPPING MOTOR uses fine STEPPING about 18° per each step.
This Module uses Transistor BC547 to be driver and uses LED to display operation of sending Logic “1” when Logic
“1” is controlling each phase. LED will be in status ON to display which phase is running. User must continuously send
Logic one phase by one phase and can start sending at any phase. There’s Pin INA, INB, INC and IND in this Module
for interfacing with I/O Pin of MCU and it makes MCU can send Logic “1” to control Step of phase rotation as one
phase by one phase. Its pin position’s arrangement is shown as in the picture below. In the Vcc part, it uses 5V power
supply and if using 3.3V MCU, must have OPTO to transform Logic from 3V into 5V.
