COPIED FROM ELECTRIC-SKATEBOARD.BUILDERS

Hey guys,

By request of @bsancken and others on this fourm, I’ve created a UART Splitter for connecting multiple add-on devices to VESC based motor controllers.

TYPES:

There are two types currenlty in the works. The two way splitter allows 2 devices to share a single UART port of a VESC based ESC. LEDs on the back of the splitter indicate when communication is taking place on any of the 3 UART ports.

The three way splitter allows 3 devices to share a single UART port of a VESC based ESC. LEDs on the top of the splitter indicate when communication is taking place on any of the 4 UART ports.

DEMOS:

TESTED DEVICES AND FEATURES:

ESCs:

  • FOCbox (FW v3.38 @ 115200 baud)

ADD-ONs:

There is plenty more testing that needs to be performed before I start selling any but I wanted to start a thread now to share the project with you guys and get your input on a some key aspects of the final product.

Yup I had to follow the crowd :stuck_out_tongue: I’ll be keeping up with both forums but I expect most activity will start happening over here now.

To ge the this thread on the same page here’s the gist of my last two replies:

I ordered the v2 PCBs for the 2 way splitter and the v1 PCBs for the 3 way splitter last night. I should be recieving them mid next week. It will likely take me a week or two to solder them up and test them. Once I am happy with the results, I will begin beta testing. I currently have 7 people waiting to become beta testers. I think I will do between 10 and 15 testers max.

I’m taking suggestions for names for this since all good products need a catchy name and I dont have any currenly :stuck_out_tongue:

How about USbR ( UART Splitter by Ricco)

I like the look of that. How would you pronounce it? I think the name should also be easily used in conversation.

Well, you could simply call it splitter when takling about it.

Thats true no name is really required when talking about it. I’ll wait a little bit to see if any other contenders get thrown into the ring before officially naming it.

Im pretty sure certain someone would be very pleased with “Dave” :smiley:

As a quick update, my timing has been delayed 1 week so I will likely begin shipping out units for beta testing in the first week of July.

How about calling it “Uriccosplit”? U stands for UART, then your nickname and split for splitter.

How about uSplit. UART-Splitter lol There’s no specific piece of hardware with that name when googled and its easy to say while still describing the function.

Or Dan! (No real meaning, just Dave’s brother! :wink: )

Also can’t wait! I just ran into where I could use these for both my boards now! lol

You know, I never looked into the DAVEga name and just accepted it as what it was. But with your’s and @bsancken’s suggestions, I wanted to find out what this Dave thing is all about and dove into the old DAVEga posts. I now realize what I’ve assumed to be a name that stands for something I just couldnt figure out actually means nothing more than people liked Dave :laughing:

Cool, we’ve got multiple options now! I’ll have to make a poll soon and let the people choose :slight_smile:

Unfortunately, due to a family emergency this last weekend, I was not able to complete the updates to the UART Splitter FW in the time frame I wanted. I was going to finished the updates and start shipping units before I leave for vacation tomorrow, but I will not be able to now. I will be back next Tuesday (7/9), will finish up the FW, and will begin shipping the beta kits shortly after.

@Ricco Wish I had known of this project sooner…I have so many things I want to use by UART. My photon, proton or davega, Bluetooth module, extra lighting systems…etc…warn me when I can get my hands on a piece of that in Canada :slight_smile:

I know the feeling! My asking for something like this prompted his project lol

@Ricco Good things come eventually, All in due time. Enjoy your vacation!

Managed to sell my soul for these, no firmware yet on em but didn’t want to pay to ship 2 seperate packages to Canada! :stuck_out_tongue_winking_eye:

Guess being on the “wrong side” makes me 20 minutes away from Lacroix and their new nazaré :stuck_out_tongue_winking_eye:
