ENNOID XLITE & VESC

Smaller size, higher current handling, CAN bus comm, open-source design & software, better reliability, better components, more configurable and can be made compatible with your own devices, etc.

USB C seems to also require 2 more 5.1k pull-down resistors for UFP USB 2.0 compatibility. CC1 & CC2 pins requires those resistors, but I’m not 100% sure to understand.

Does anybody here could help/confirm?

Correct and in section 3.2 is the value with 5.1k

But if everyone wants Type C, why put something else in?

To show the manufacturer what most folks’ second choice would be, if Type C isn’t doable for technical or logistical reasons

yep because usb c can be both a ā€œslaveā€ and ā€œmasterā€ (don’t get mad at me for the terms its just what they are know as). so you need to have some way to tell the master what its connected to, as this device is a slave it needs 5.1ks to ground on both cc1 and cc2

edit- i have used this connector before and its by far the best iv come across (if you are using usb 2.0) it only has 12 pins (technically 16 if you count the grounding pins) this makes it much easier to implement and solder. (i have an eagle library if you need)

Would go with this vertical one:

Lol completely forgot to actually post a link to the one I like https://lcsc.com/product-detail/USB-Connectors_Korean-Hroparts-Elec-TYPE-C-31-M-12_C165948.html but yea fair enough if you want to go with a vertical one

All other connectors on the voard are vertical, so I don’t think it would not make sense to have the USB horizontal. Also space ia limited & vertical takes less space

15S version with USB C, isolated CAN IC & more GND pins for all 9 thermistors.

Happy everyone :stuck_out_tongue: ?

Not until it’s available on the 18S version :stuck_out_tongue:

I confirm, both 15S & 18S boards use the same design. So you can be happy now.

Only the TVS protection & the LTC IC used for balancing are the only difference between both boards.

I just posted a picture of 15S version because I never had before.

When can I buy the 18s version? Do you have an updated timeline? I have a davega and really wanna see my cell voltages on my 16s build.

I ordered last week 160 LTC6813 18S IC directly from analog device, but they are back order, expected delivery in 10-12 weeks…No parts available at suppliers neither.

I have approx. 150 LTC6812 15S IC in stock, so the 15S version will be available before the 18S version unfortunately.

There is some positive to the part shortage thought… I’m now working on dual sided component PCB, so the target is to reduce the overall size to 60mm x 100mm for the full version & 60mm x 60mm for charge only version. It fits so far, some routing left to do, but I had to throw away the optional BLE module. Don’t ask me to go smaller, it is extremely compact! Hope that everyone will be happy now :slight_smile:

Now you’re talking.

I’ve only used the DieBieMS once, and found the documentation left a little to be desired. Will you be providing solid documentation and troubleshooting information?

2 Likes

For doc, it should be better. At least a connection scheme & some videos to show how to use the app & troubleshoot. The tool app has been improved on some aspect too.

JST PH for all connector is also more common than the connector used on DieBieMS (molex picoblade connectors & wurth wr-mcp3), so it should be easier to get started with this version.

Vertical or Horizontal - I’d think hortizonal will have the best logevity. got a few vertical usb C. Unity/Flexi… But Horzontal is best for most applications still the same spot (much like diebies)

I would consider XH as well. what a huge amount of li-po packs use as balance lead connectors

No way xh 2.5mm connector can fit there. You want small package or what?
