MICRO Module

Hi,

since many people - including myself - require specific requirements concerning power, size, connectivity and price, I decided to develop a small SMD solderable module that contains the electronics of the VESC 6.

Github project:

https://github.com/FabianViermetz/VESC-Modul-Hardware.git

This board shall simplify the development of highly customized boards ranging from super small layouts for copter use up to high current (>100A) applications. You only have to design a carrier board which contains the power stage and the communication periperals required. 

Since this board features the DRV8320RS which has a inbuild deadtime insertion, it works with a wide range of Mosfets since no deadtime needs to be determined and set in the firmware.

 

I will keep you updated when i get it running.

 

If you have any ideas or suggestions please let me know! Also I would be interested in how you like it so I can decide if I produce a small amount of them for a cheaper price.

Is there any plans to use the DRV8353R?

hi,

the benefit of the DRV835x over the DRV832x is the voltage. I thought of it allready, but it also features a much smaller buck regulator which limits the connection potential. also it is bigger, which is a problem and finding parts especially Capacitors for 60V was hard enough on this footprint. Since i wanted to create a as small as possible footprint, i decided for the DRV8320R. 

I will definately not use the DRV8353R. I dont know how good sensing will work with such long shunt sense routes and it also reduces application diversity since it is low side sensing only. 

Do you agree? Did I miss something you were thinking of?

I will wait to see your implementation since it will work for the majority of applications.
