Hey there-

Glad to see you made it over. Welcome!

Not sure why we haven’t seen more locking connectors in esk8 electrical components. Sometimes it really feels as if those designing them have never actually looked at JST’s catalog or something…

Please revise micro-USB to USB C :wink:

Looks good!
How is real-world testing progressing?

good point! actually this is just a working prototype. I could add a C port in the next version.

With shipping to the USA we could expect to pay?

Nice little ESC!

Does that mean just 20A continuous battery amps ?

This design is wonderfully thin without the heatsink.
Suggestion: use a smaller copper heatsink with bigger mass but much thinner profile.
If you can get it down to 10-13mm, one could stack two of these and they would be similar height to the batteries -> ideal for a cramming a 4WD in a board with integrated enclosure.

For battery current, when I did the test, it was around 40v 20-25a. Really not sure its potential, because I did not find a larger motor to test it.

For the heatsink, you could just customize by yourself. There’ s no component on the other side of the pcb. you could even attach a water block on it.

I like that. In that case, I would recommend removing the connector on the other side making sure it’s flat. Like that it can be directly glued onto a heatsink (such as on some enclosures)

Sounds like you need some testers.

What is your expected price? I would love to test a couple of these on 13s

i really need a single motor esc, my fesc6 really isn’t working out.

Photos are nice!

These are 1.25mm pitch? Nonstandard, So hard to crimp, and takes only very thin easy to break wire?

Awesome. Love seeing new options hit the market. Welcome aboard and I’m curious to see what this has to offer

Awesome formfactor, good job!
Design looks thought through. How is it managin without any electrolytics tho, how much cap could you fit in just the ceramics?

Good that you did a contineuos 1kw test. But…you did test 13S that you claim? Or are you just refering to maxvalues and thinking its cool?

Did someone make an official esk8.news torquebench yet where we send samples to get them tested?.. Feels overdue :zipper_mouth_face:

Nice compact design, I see there is some space left for CAN header. Maybe you can consider adding it :slight_smile:

LOL. I just wanted to make exactly the same comment. :laughing:

Pardon the silly question, but why is the heatsink on the opposite side from the FETs?
