I’m behind in sending out stuff at the moment, and next week I’m away for work, so it will be next weekend before I will send the next boards.

for the Convoy Nichia LED I would strongly advise to make a resistor parallel to the LED which eats up 200mA
R=U/I=3.8V/0,2A=19 Ohms
P=U*1=3.8V*0.2A=0.76W

mine on this star is dying, lost about half its output
I used that light more than 20 minutes continously some times and its not good at 700mA

Yes I do, 3 boards is fine, and thanks for the PM. I will reply this weekend because I’m not at home atm.

In general, I have so little boards leftover that at this point I stop the sale. Will update the OP and title.

These would be a nice addition to Clemenece’s new online shop I think.

Clemence has a version in the pipeline if I’m correct that should perform better than this board.

Hate to revive an old thread… but anyone know where i can find a few of these boards for the Nichia 119? I have a couple dozen 119’s that i have a project form, but no boards to put them on.

I think the clemence PCB’s will work with the 119. I would contact him.

Yes, the VirEnce VR16S1 board will fit the 119’s fine, but are a bit overkill at 4 dollar per board.
The boards from the OP were not cheap either and are unfortunately sold out, I had 200 of them made and sold most of them and have only a few leftover for own use. And it seems that you need many. I see no source for 119 boards on the internet atm Sad

So sorry, that USD 4/pc is there for unlucky reasons. For anything below 10 watt it’s overkill. Any cheap non DTP board will do just fine. Try Digikey or Mouser.

You should buy S2+ UV Nichia 276A very early, I changed the aluminum plate to copper plate for several years.
