New UC300ETH breakout board.

[Beefy]

Don't suppose their is a beta PDF manual we can download to learn its' features. I'm quite interested in this board.

At the moment I've got several of Homann Designs breakout boards, but they don't have opto isolation and having several of them around my UC300-ETH (one for each port !!!) really takes up a lot of board space and the wiring looks rather messy. Apart from that they are a highly configurable board.

And I had to make my own mini opto-isolation boards too. So this new UB1 board solves all these issues in one hit.

No, there's no manual yet. He mentioned he might need some help with the manual, as he doesn't speak English well.

But, I think that it's very similar to the MB2, feature wise.
Looking at the pics, the main difference is the addition of two analog inputs.
The UB1 has two analog outputs vs one on the MB2.
The UB1 has 3 relays vs two on the MB2. But looking at the pic, it looks like the relays are all normally open, where on the MB2 they can be NO or NC.

Other than that, it should be mostly the same as the MB2.

OK, cheers Gerry.

Hello,

I’ve been busy on testing and making change to the new version of UB1. After sending a new version to PCB manufacturer. Now I have time to shoot video and pictures for updating you guys.



The video will show you various parts of the board, the testing environment. The attach pictures, in the red circle shows a mistake of wrong pin mapping. The orange circle is a stealing Y401 for ordinary analog output.

I traced a hundred of signals from UC300ETH that communicate with 5LPT mother board, but missed out one signal. The UB1 will be 100% pin out compatible with 5LPT mother board except PWM analog frequency.

The UB1 borrows opto isolated analog circuit from MB2 which runs PWM at 1 khz, but 5LPT analog circuit runs at 48khz. The analog circuit of UB1 acts as potentiometer and need to consume small amount of power because some VFD drives supply small amount of power for potentiometer.

Solving incompatible problem, Balazs will help me by adding an identifier for UB1 board. Next time when UC300ETH boot up, it will sense this identifier and change the PWM frequency that suitable for UB1 board.

I expected that to have UB1 board finished for sales within 3 weeks.

Thank you,
Weerasak
PS. Somehow I lost an email from the New Zealander during my busy days. Please re- email me again.

Great work, the board looks good.

Great looking board and nice video man.

[ger21]

Yes, very nice.

Hi Weerasak

The board looks great. I mentioned on the UCCNC page that controlling 12v and 24v solenoid coils on air valves have consistently caused noise issues for me on a variety of boards. Any chance of you testing the board with a couple of solenoids?

Thanks

HI Derek

OK, I will find a solenoid coil and some others inductance loads then do a test for you.

I see the UB1 is now listed on the cncroom site.
Currently it's zero stock but as soon as it's available I will be ordering.

At $180 it's more money than the MB2 but I still think it's a very good price for the feature set.

[ger21]

It's more money because it has a lot more components than the MB2, due to differences between the ESS and UC300ETH.
The UB1-UC300ETH combo is still $90 less than the ESS-MB2.

I believe that the next UCCNC update should have support for the UB1, as CNC Room is currently doing software testing and working out some minor issues.

You also save the cost of not having to buy a 5LPT with a UC300ETH.
