    how about an Audio Shield Lite?

    Hi Paul. I've been playing with the Teensy + Audio Shield in some guitar pedal projects and it's super cool. But space is at a premium inside pedal enclosures, and the Audio Shield part is relatively big.

    Have you ever given thought to a narrow variant? All I need is line in/out, no extra memory or headphone output. It would be pretty killer to get an audio Teensy down to the same footprint as the regular Teensy.

    I'll attach a pic of a pedal build - this is a copy of that "pedal that can experience suffering", which you posted on the pjrc blog recently, with the Teensy on a simple PCB I threw together. I could definitely make this layout more compact but it illustrates what I'm talking about.

    Cheers!

    I haven't actually assembled it yet, but PJRC does a kit with a PT8211 that sits on top of the Teensy. There are 2 PCBs included in the kit, one for the Teensy 3.2/3.5/3.6 and the other for the Teensy 4.0/4.1. It has some soldering involved (both SMT and through hole):

    Ah interesting, I hadn't seen that! Looks like outputs only though.
