Power Header for PCB #4

Closed anthonyjclarke closed 5 years ago

anthonyjclarke commented 5 years ago

Hi

Thanks for all your Dev here, brilliant.. you should have a "Tip Jar" :)

Will order some 1.4 boards, before I do... I noticed that the Power Headers I bought from Aliexpress - http://tinyurl.com/y7eymwsj do not seem to fit the PCB. They align with the Power Cable from the displays I have.

Is this my error in ordering? or the wrong connector on the PCB?

Thanks

hallard commented 5 years ago

Correct, this connector is 3.96mm was not aware about this one, I knew 3.50mm or 5.08mm one, I'll change the PCB ASAP Would you have one to send me by postal service ?

anthonyjclarke commented 5 years ago

No need to send, I will order when you have updated the PCB :)

Really appreciate your help here!

Built another version today... using a more compact LED display - P2.5 64x32 http://tinyurl.com/ycgdvj3t , so may have to think about the display connector again...

Bit too close to the power connector...

Damned, it will start to be complicated best would be to be able to plug also on the power connector ;-)

@hallard Could I please ask a big favour :) Going to order from jlcpcb.com some 1.4 boards (quicker than pcb.io) They have just told me the gerbers I created from Eagle are not valid, is there any way you could export gerber files and share (please) ? :)

hallard commented 5 years ago

@anthonyjclarke I'm using Eagle also, that' strange, default settings doesn't work. Which CAM job did you used to generate gerber files? Does jlcpcb provide any cam job to generate gerbers? Anyway I've put gerber file on the repo (used SeeedStudio CAM file as always) and that's for Matrix Shield Board Version 1.5 that should fix you issues ;-) Pcbs.io and github repo have been updated to reflect new changes Let me know if gerbers are ok.

anthonyjclarke commented 5 years ago

@hallard Thanks for this... Looks perfect, like the new version... IF there ever is a 1.6 then I've had some issues in Temp Sensors being so close to the Wemos / perhaps move that to the outside of the board.... I may mount on wire in any case. Thanks again!

dragondaud commented 5 years ago

I'v been using waterproof DS18B20 which come on a long wire, but I put clocks inside shadow box frames, and I wanted the temp sensor outside of that, even.

hallard commented 5 years ago

Yes, I had some problem with NodeMCU board when I but SI7021 on board shield sensor, temp sensor need to be far from CPU board, because value is higher than real. May be adding an "offset" option could help, but the best is the DS18B20 waterproof, just a hole in the case to get sensor out.
