Need Help for a Custom Board 80V 35A

Hi @Juan-Antonio_Soren_E
Sorry for my late reply, I got Covid few days ago and felt a little sleepy

@Juan-Antonio_Soren_E

Let me know if you would like to collaborate on the stack format/standard.

When I started this project, I mostly wanted to use available and affordable components so I can make a prototype without spending too much money. I’m totally new to SimpleFoc and I started this project mostly to learn and use it with the big motors I have in stock. I’m not that experienced, but I’ll be glad to help you in your project. How far are you in your project progress? You work on KiCad?

About the FETs footprint, in my point of view, the best would be to use the most standard one so it’s easily replaceable.

The challenge of double side components can surely be overcome. I can reflow it if need be. Where are you located?

It seems JLCPCB also offers double side mounted now, so it’s not a problem anymore! I’m located in France but I have a reflow station too but if everything can arrive mounted and ready to use, it’s more convenient Thanks for the offer. I used to assemble the PCB by myself before but then I found SMT service on the internet

I just right making something simillar.
This is a VESC compatible focer without DRV8301 but FD6288. Named PingFocer, the size is 40x60mm. So far it’s tested under 50v and is capable of handle over 500W. Still I’m looking for a way to absorb more mechanical power so that higher limit I’m able to test.
Since it got build in low side current sensor and its based on STM32F405, I thought its easy to use with SimpleFOC. In a few days I’m gonna to release the full design to the com
munity after more test. Besides ,its “JLCSMT compatible”, everything is on one side except MOSFET and the sense resister.

Looks great! Mostly if there’s no DRV8301. Do all VESC are hardware compatible with SimpleFoc? Because I have one in stock so it would be quicker for me to test SimpleFoc with a “higher power” motor.
