Ok...my bad. I didn't understand your initial question. But now the next question is: what do you want to accomplish exactly? Can you be more specific?

[mtiutiu]

@tonnerre33

Thanks for the pics and for your time. Well that's how the SOT-89 package is designed. If I'm not mistaking the big metallic pad was made like that for better thermal dissipation if you make the copper area which it connects to big enough. Now why it was specifically connected to Vin...that I'm afraid I don't know.

@mtiutiu I ask you to help me connect ESP-01 to your board

[bjornhallberg]

Just want to confirm that I also received a "VL-C702X-2 VER:C1" today in the mail so at least they haven't made yet another version.

[tonnerre33]

Hello @mtiutiu i think i have finished my first version.
I have modified the pcb with your suggestions (power the node with 12VCC).
I have corrected a big mistake too, the AT25DF512C footprint was wrong (convertor mistake i think) ...

I have to put 2 resistors on the prohibided face ^^ but normaly it should be ok

[shabba]

So besides the header being bigger what else has changed? I have received the current PCBs and wondering what I might need to do to make them still work?

[tonnerre33]

@shabba said in 💬 Livolo 2 channels 1 way EU switch(VL-C700X-1 Ver: B8):

The position of the header has changed too. Now it's on the right part.
I think you can use your pcb but you'll need some wires between the femal header and the new mal header.

@tonnerre33 Thanks - do you happen to know the pin out?

[tonnerre33]

Yes, you can find the new pint out here :

[shabba]

@tonnerre33 Thanks! Do you know the old one?

[hhalibo]

@tonnerre33 I just browsed your Github repo, found nothing there today, you deleted the contents？

[hhalibo]

That's my fool. I saw it in the develop branch.

[tonnerre33]

@shabba You can see the old one on the picture of this project ;)

@hhalibo Yes i'll push this project in the master branch only when i'll have test it. @mtiutiu is working on it too, i did this node for training me because i'll develop other livolo EU ;)
I think the mtiutiu node will be more optimised. I learned and i hope continu to learn many things with him.

[shabba]

hi @mtiutiu - I see https://github.com/mtiutiu/kicad/tree/master/mysensors/node/livolo_EU_switch/VL-C702X-2_Ver_C1 - Is this good to be ordered? If you give me a link on where you get a % I would like to order from there.

Thanks.

@shabba

It's not finished yet. That's just a draft for the upcoming new hardware. When it's finished I'll publish it. As I said all of my work is done using my free time. For now I'm on vacation...will start working again on this project next week.

[shabba]

@mtiutiu I was not meaning to sound pushy! Enjoy your vacation.

[dzungpham0703]

How about this project now?

[freynder]

@dzungpham0703

It is abandoned, have a look at the description.

[dzungpham0703]

@freynder Yes, but he start new project here https://github.com/mtiutiu/KiCAD_Playground/tree/master/mysensors/node/livolo_EU_switch/VL-C700X-1_Ver_C2/CYBLE-012012-10

I replied in the nrf51822 thread. Yes I managed to make it work like the original with BLE stack. And using the wonderful Cypress Proc BLE solution including capsense and lots of goodies . Cypress really rocks! I love them.

The current consumption was lowered to 200uA without being connected and 700uA connected. Those numbers include LEDs current consumption and other blocks like touch sensing.

I'll get back with more updates when it's finished.
