The stepstick driver (A4988) is not working (turning motor). Have 5V from logicGND to powerGND, this after jump from breadboard when was working. get a little warm when connect both GND without load. haven't connected motor since. Is there something to do or is burned?by giancarlocp - Stepper Motors, Servo Motors, DC Motors
Dear community, I am searching professional opinion about Powerlolu working with NexFET Power Blocks (see slit127.pdf) CSD87353Q5D to use 4 dual NexFET instead 8 HexFET. Sadly lacks built-in reverse diode, so need 8 shockley diode. These can be found in mouser and digikey. My regards.by giancarlocp - RAMPS Electronics

Hello balestrino, i see your pcb layout in github, +1. I'm thinking to test TI's NexFet Dual package to reduce pcb size. Do you think A4989 will manage these well? If you can take a look at these Mosfets. Regardsby giancarlocp - RAMPS Electronics
