Hello!I live in Brazil and I can not find the driver DM542T, can I use the driver DM542 instead?what is the difference between them? i have not been able to find out what the T stands for
The 'T' is relevant to the StepperOnline brand. This is the brand that @Chris Annin uses in the manual. Any quality DM542 microcontroller should suffice.
yes, i tried it look the same.
