Can anyone help? 
Let me apologize in advance for being too lazy to figure this out myself, but can anyone offer a real quick summary of where this stands?
Is this tested, released, and reasonably stable currently? Parts readily available?
Thanks.
Hi, Im new here but hopefully I can help a little by giving you my experience so far.
There are some confusing things about the documentation and some problems I ran into but so far I have built and lightly tested 1 motor controller and it seems to be running fine.
The ordering process
When uploading the files and placing the order with JLCPCB I had to manually rotate some of the parts that where placed wrong in JLCPCB’s design viewer but the guide on Github explained it well enough. JLCPCB did not reject the design for having more than one board per design like some other users have reported.
2 of the parts needed where out of stock.
. I replaced the 600ma 30nH inductors with 420ma 30nH inductors (so far they seem to work fine)
. The Bosch Sensortec BMI160 is out of stock and out of production so I had to buy idle parts from one of the other JLCPCB users selling there stock, it was an easy process and a list of people selling there stuff is shown in the bottem of the info window when you click on the little magnafying glass. There where about 50 BMI160 left when I ordered mine.
The build
The build guide in the Github repository has lots of sections that do not completely match the current version-1.0 state of the board design but is mostly right.
The design now uses machine header pins instead of standard header pins and now the “free-pill” clips onto the underside of the main board using these pins. This design seems to work very well but the pictures on the build guide show the old design with all the pins on the bored being flipped relative to the new design.
I have gotten one controller built and it seems to run just fine on my test bench. I will post some more details later about the build along with pictures. If you have any specific questions feel free to ask.

Thanks very much for that summary! Very helpful. I’d kind of like to build a couple of these, but I’m not in any hurry. I’d prefer to wait until all the doc is updated. I don’t suppose anyone knows if that’s still on the menu?
I am using it since july . Its very capable. I was going up mountains, trails and it does everything I asked for. The big issue at the moment is that the bmi160 can not be ordered right know so i redesigned it to use a new gyro. the thing is this is not tested but i think i will order some this week.
best regards,
Markus

My longest ride with a vesc onewheel 20s was 45km nonstop in the sommer heat. Everything worked flawless!

I don’t need the IMU, so I assume it’s OK to simply not populate that part - right?
yes thats fine

Hi everybody.
So I’ve been back from summer holidays about a month ago, but have been busy at work and some repair stuff on my sailboat.
I was working on the mechanics of my own one-wheel, but I must admit that the project has stalled for now because of a lot of other things to do.
One thing I need to do is to pull out the 35 year old 250 kg diesel engine from my sailboat, because it died over the summer. So now I have desided to go all electric on the sailboat, using VESC technology. For the batteries I will go with 23s of 320 aH lifepo4 (equivalent to 20s li-ion), but shambler00117 already tested the 20s configuration, so I guess it works 
I have already ordered the batteries trough Alibaba.com.
I will order 3 x 8 kW motors from China (QS165), and a single FreeDRIVE should be able to handle 8 kW (at 84V). So I will need three drives connected over CAN, to drive all three motors. Ultimately, I hope I’m able to do regeneration when sailing with sails, to put power back in the batteries. You know, the propeller will spin in the water, and then I will try to break it, and thereby do regen.
The first thing I need to fix is the PUSH-BUTTON issue - and I think I will start soon. Think I will remove my pure hardware implementation, and go with a more standart hw & sw solution, so automatic shutdown also works.
Then I will probably wait for Shambler00117 to finish his tests on the new IMU, and if it works, it will just be pushed to the repository.
Sorry that I have not been is this forum for some months - but good to see that there are some capable people that have been able to solve some of the issues.

And I’m still slightly frustrated that I cannot edit all the misspellings of my previous post, but that’s how it is. Seems like I need to do a lot more reading in other thread, create new treads, etc. in order to be knighted and get the noble title of Sir FocKing and all the wonderful privileges that come with it.
@jamie could you bump Jens to Level 2 so he can edit his posts and whatnot? I’d say his contributions with this open source ESC project justifies it.

Hope you managed to pick a non scammy supplier

Especially on a boat, last place I’d want to be stuck with poofy and or internally shorting batteries.

Just compiled FW6.05 no limits if anyone is interested. Tested on the bench with a 63100 Outrunner.

I did that as well but with the 20s file. Which I need for my builds

Good seeing you back It would be awesome if we could put a vesc express over CAN BUS directly on the board and also the switch would be great. Now I am even using the onboard 12v BEC for 44 RBG LEDs (22 FRONT / BACK), it works great
Thats why i waited with ordering on the new IMU Version so i could test it with this 2 additional things as well. I also put a fork of the 20s Version on my git as well.
One thing: last time I ordered a Version 1.0 from JLCPCB wanted to charge 3 designs because of the tabs. In order to avoid this we will need to put everything on one board otherwise it gets more expensive ( the wanted to add 60$ on top of the 5 VESCs) , but i really don’t know how to keep it as compact as it is. So maybe we will need to pay the add. charge.
Other than that this VESC is awesome. I am torturing that poor thing (85 Celsius on the mosfets :D) , but its working no problem
Looking forward on getting this thing to Version 2 
best,
Markus
and for the boat stuff some EVE 280Ah or Envision ESS 4LH3L7 280Ah should work great. 2 Weeks ago a build a 16S Pack for my PV which works great .
You can get the for really cheap at:
my next project is also water related, i am a kitesurfer , BUT there is not always enough wind so I want to build a e-foil using VESC to keep surfing

You do it the other way round, I first built an eFoil (or two) and now start to build a onewheel…
