You can tell JLCPCB to assemble how many you want. I set it for all 5 assembled. Add the FETS, Caps etc separately, about $200. More than I want/need.
You get to pick either a nonnegative multiple of 5 … or two. Those are the only options. You can’t get 4, 16, -5, or 1. You can get 0, 2, 5, 10, 15, 20, or 80000.

Hi
Number 1 out of 5 assembled, tested and working.
No big issues with the assembly.
Best regards

The Bosch page surprisingly doesn’t specifically call out the replacement imu, most seem to have the same package size.
I took a look at the new BMI323 (which also specifies low noise) and BMI270 (low power) which appear to be the same package size, 323 differs from BMI160 in the callouts for pads 2 and 10, BMI270 seems to have an identical pinout. (I haven’t read into them or the other options in any more depth than that)

BMI260 and BMI263 look interesting for the self calibrating gyroscope, not sure what impacts that would have here.

This looks awesome. 
So you did the assembly without swiss machine headers, and with the mcu board on the top side, which is also perfectly alright.
INFO: If you connect a momentary switch - the first time you connect it might take up to 1 minute before you can switch it off again. This is because the capacitor needs to charge the first time it’s connected. I can probably do better in v1.01, but I wanted to build the momentary-stuff-circuit from jlcpcb-standard components to keep the extra price only at a few cents.
I’m a little confused. Does vesc 6 software support anything else than BMI160 and MPU9250?
took some time cause i did diy the rails and everything on this board xD
Hey guys I am looking to order a few of these from JLC I want only two if anyone what’s to do a group buy contact me on discord at Bazing89.
This looks really gooood… Very impressed.
I’m in the process of making such a thing too - an Unwheel. But, I will make a timing-belt & pulley version of it. Don’t see why that shouldn’t be possible.
So you made the rails yourself? What about all the other printed parts, are these your design or did you get the STLs from some site? Sorry, I’m a novice.

The middle part of the rail i ordered from JLCPCB (designed it myself) . The outer parts are from a 40x20x3mm standard U-Rail i bought and adapted. The first onwheels worked with belts, but this special hubmotors are more responsive and very strong (expensive as well 
)

Sorry, but I have to ask: What was the price for ordering the CNC-machined part from jlcpcb?
Not that expensive:
If you have a look at the rail center part it was $157.74 including shipping and tax (2 pieces with threads)
for smaller parts it was around $50 (2 pieces no threads)

I’m trying make aluminium rails with some late Stone Age technology.

I am on the finishing touches of my vesc board. Therefore i compiled a custom 6.02 VESC Firmware with Voltage Limits 20V and 90V (20s) . It was working with my 100V Caps. Here is the firmware. I hope nothing of the hardware is over the 84V max
FOC_KING.bin (512.0 KB)
Do you have the source code available for this binary?
yes
May we have it please
