New PCB overview...

<< < (2/2)

martindunne:
hi there are now four LEDs on the front panel,
will keep with LCD for now but good design = easily changed when i feel a need for a change, maybe oled ?

pld:
Looking closer at the pictures, it's pretty obvious: L2, L5... I just don't recall seeing anything in the source though :)

I saw a Shruti with a white OLED but couldn't find one in 20x4. But now that I think about it, I might have an unused VFD lying around that might be compatible.
Might use too much power though...

martindunne:
ooooh VFD they look good

Xavier:
LEDs: There are 4 leds in the new PCB... but there are plugged on one single output. Same output as with previous PCB.
There's not information shown by those leds except blinking in sync to external midi clock.

The OLED i use and which will be in next Kits are the yellow newhaven:

I also tried the blue ones, but unfortunately they are very VERY noisy.
The yellow version is silent.

Please share if you have any source of different good displays  :)

Good to know, that was my other favourite :)

According to the datasheet the VFD (Noritake GU140x32f-7806) should have fit mechanically, but mine has a smaller PCB so I'll need to hotwire something.
Not sure if the logic levels work (cerb40: 3.3v?, vfd wants 3.5v min) but I'll give it a try. And if it works I'll open a new thread ;)
