Title: Modular PT2399 pcb daughter-board?
Post by: anotherjim on September 14, 2016, 09:54:50 AM
Meaning a little, narrow pcb that carries a single PT2399 (preferably smd, or PDIP or possibly both in the same area?), has connections via right angle or straight 0.1" header pins along one edge and has pads for the standard support bits (4x 100nF & power caps). The op-amp/audio pins all go to the header pins only. Maybe pads for the pin 6 time setting resistor too.
Does anyone know if this already exists? I think it would be really useful for multi delay projects.
Nearest I've found is this...

Which isn't as basic or as small as I'm thinking of. The PT would be horizontal so it can be the minimum width.

More like this format...

Only the minimum, standard caps would be on the board (6 or 7). 5 volt regulator, Pin6 delay set and op-amp R/C's would be on your main board.

Have you found what you're after?   If not,  if you draw up a schematic I'll lay it out and etch and drill a batch.

Wow, that's a generous offer Nick. I'll give it a go.
I'd just noticed that Bitsbox have smd PT2399 for 60p, half price of PDIP!

No problem Jim,  you've helped me loads over the last two years.

Eventually. Blame it on the crap weather here at the moment (ok if you're a duck). & I hate doing graphic work on computers.

Isn't it cute?

Thoughts?
