4. What do we changed comparing with original version?
4.1 Added a RESET button
The RESET button is used for forcing the hardware to reset. It’s similar like the power on/off button in your mobile phone.
4.2 Added an ISP button
The purpose is to provide one more way to do firmware upgrading.
4.3 Increase the capacitance(2.2 uf)on the GVDD power circuitto fix the DVDD failure of the original hardware 3.4 version
4.4 Modified the USB interface toMini USB( UX60SC-MB-5ST)
4.5 Modifiedall connectors to more applicable for operation
4.6 All connectors are installed to the BOTTOM sidefor better heat dissipation performance.
4.7 Added motor grounding pin line for some motors that may need to solder the ground circuit.
4.8 Enlargethe soldering pad hole of DRV8301 chip to lessen void soldering chance
4.9 PCB processing technology: PCB adopts a gold-thickening process with a 2 layer PCB layout design. 2OZ thickness.

Hobby Motors For Robotics
Stepper motors are ubiquitous in hobby robotics projects: If you make a robotics or automation project today, it is very likely you will use them. Almost all DIY projects from 3D printers and CNC mills, to various custom robots and automation solutions use them. However in industrial automation, brushless servomotors have taken over, and it's clear why: They don't lose steps, are much more powerful, efficient, and silent.
Brushless motors are not unique to expensive industrial automation equipment. In fact, you can get some very powerful and cheap motors at hobby shops. The electronics to drive these motors are also dirt cheap. So how come virtually no non-industrial automation systems use them?
To be honest, I have no idea. Seriously, a driver that allows this should clearly exist.
But since it didn't, I decided to make one.
And you are invited!
This project is open source, both in hardware and software, and I warmly welcome anyone who wants to join.
