Wiring and running TB6600 stepper driver with Arduino
A quick post about wiring TB6600 stepper driver which is based on TB6600HG chip. Here I use one without black plastic casing. It has model marking on the back that says “BL-TB6600-v1.2″. Stepper motor used in this demo is 23HS22-2804S (2.8A, NEMA23). Drive looks like this and it’s rated for 4.5A. Looking for more info and photos?

How to use H-bridge HG7881 (HG7881CP) module with external power supply and Arduino UNO
First-time use of H-bridge HG7881 (HG7881CP) module was pretty confusing for me. I didn’t find good (if any?) information about wiring this module up and running it with Arduino. But same time it seems to be quite popular. Here I share how I connected it to an external 12V power supply. You can use any other voltage
