Vedder released the first images yesterday! The new version is a 2 piece design with Direct Fets and heat sink. This unit also use the DRV8301 since TI seems to be phasing out the 8302 on the original VESC. Ben has put a lot of effort into making a more robust design and it should also work on a wider range of motors. This version will have a much higher constant current rating virtually ending the overheating issues faced with the older modules.
This version will likely need +/- 3months to be anywhere near usable for “normal” People in the most optimal case ( judged by Experience ). Software needs to change and PCB routing looks far from ideal.
Be sure to practice on some scrap electronics. Quick tip, you can use a tantalum capacitor to see if you get things too hot. They will darken or turn brown if they get too hot. A good visual aid when dialing in your hot air temps.
@JTAG Yeah, it will be a little while. Vedder stated he will be doing some rerouting of the ki-cad files but will be ordering parts within a week. Don’t hate on us ki-cad users Plus this is not a completely new design, I highly doubt it will take Vedder that long to work it out.
Care to explain? Obviously there are a few things that have yet to be routed but I am having trouble seeing what you are referencing. This version is much less crowded than the previous versions. This would be useful information for others designing their own electronics.
Could it be you are referring to the first picture?
There are obviously layers there that have not been routed yet on that picture but it is also obvious that would not be the final version.
All other pictures show decent routing and I doubt internal layers would be overlooked by Vedder.
I won’t speculate too much on the release of the gerber files but I know of no better way to support Vedder than building his designs to the best of our ability and sending him donations from the proceeds. You know we will be on this from day one.
Best thing to do right now is send him some $encouragement. Building these controllers in small quantities is expensive. We are a really lucky bunch to have a person as brilliant as Benjamin develop electronics for us.
How could I forget to mention Vedder is designing a case for this version too! It will double as a heat sink. Basically this module will have the power of a high end car ESC with the plush throttle response we have all grown to love from the VESC.
Oh Snap! These are great developments! Can I pre-order V5 now? LOL
I love the idea of the heatsink/case. So is this rev change going to solve the issues with FOC? Is it going to be less finicky with 12s setups?
