I got my sammichFM second hand so I didn’t get to build it, but I looked around on the board and didn’t see anything obvious to setup an AOUT module to add a filter. I’m sure it could be customized, but I thought I’d seek pro tips on if AOUT’s were planned ahead for with the sammichFM.
Could you use a shruthi filter?
The AOUT needs to be connected to J6 on the “core”, which is part of the lower pcb in the sammichFM.
It’s near the edge opposing the connectors. You will need to make J6 accessible from the outside, or change the enclosure somehow, as there is not much space left inside.
Maybe a custom PCB with AOUT and filter would fit, if built REALLY flat (like <10mm max height).
You’ll also need to activate the AOut in the firmware. I don’t know about the shruti filters, they might be adaptable, but surely won’t be ‘plug’n’play’ as in the shruti.
Awesome. Thanks for the reply! At the very least I can use a cheap homemade filter.
Break out cabling it is.
