Meet Pisound Micro - All-in-One Hat for Your Audio Projects

Announcements

Good day, everyone!

Since the original Pisound was launched, we have been receiving a wide range of configuration requests from people using Pisound for their custom audio hardware projects and small manufacturing runs. Be it changing MIDI DIN-5 ports to 3.5mm jacks, removing Audio IN altogether, a version without potentiometers, and so on. So we decided to create a board that could bend to any build. The result is Pisound Micro - a super-flexible, tiny platform for bringing your custom audio hardware ideas to life!

Main Pisound Micro Features

  • Audio: (Un)Balanced stereo IN & OUT, 24-bit / 96 kHz, ~ 5 ms loopback, > 98 dB SNR
  • MIDI: 1x IN & 1x OUT, 1.4 ms loopback, optional activity LEDs
  • GPIOs: 12x 10-bit analog + 25x digital, 0.5 ms latency
  • Footprint: 56 x 65 x 4 mm, 13 g, draws just 25-35 mA
  • Pin usage: I²S + I²C + only 2 additional SBC GPIO pins
  • Connectors: None pre-soldered - spin it, flip it, panel-mount it, or tuck it under an OLED

You’ll Love Hacking with It!

  • Great low-latency audio: for pocket loopers, noise boxes, or headless guitar pedals.
  • Clock-tight MIDI: keeping your projects in sync!
  • 37 extra GPIOs: read pots, encoders, drive relays or LEDs without stealing Pi pins.
  • Battery-friendly: 25 mA idle keeps mobile builds alive for longer.
  • Open-source software: “libpisoundmicro” library, a physical control configurator/mapper, plus Patchbox OS images tuned for < 3 ms round-trip.

Beta Program & Early-Bird Batch

As with Pimidi, we’re opening the very first run of boards exclusively to the community to gather feedback before the public release.

Also, Pisound Micro docs are live! You’ll find a quick-start guide, wiring diagrams, and code samples to get you rolling. We’ll be expanding docs further, so if you spot something that’s missing or have a clever idea, let us know!

That’s it! We’re super excited to see what you’ll create with this tiny beast - let’s keep building!

Cheers,

Blokas Team! :heart:

Congratulations Blokas on the new product! I’m definitely thinking this would be a great product to create an “all-in-one” MODEP stomp box! I’ve been thinking about how to do that with the regular PiSound and this just adds a ton of flexibility plus you could easily add footswitches as well.

This is cool!

For the docs:

Could you explain how to correctly solder and setup an Endless Capacitive Encoder (incremental and touch sensitive)? For example for sending midi CC.

And it would be nice to have a few direct product links to compatible connectors, capacitors, encoders and appropriate electronic parts.
