Keybow 2040 with Adafruit STEMMA Speaker

[kjw]

I’ve been working on adding audio to the Keybow 2040. I’ve not finished all the code but I’ve got the hardware and a demo working now. The addition is fairly straightforward, it just needs new 12mm spacers to replace the supplied 4mm ones and two passive components to make an RC filter to tame the PWM carrier in the audio.

More excitement:

• an article describing the speaker addition: Instructables: Colourful Macropad With Audio Using Pimoroni Keybow 2040 and Adafruit STEMMA Speaker (HID + MIDI Capable)
• the Keybow 2040 is on sale to celebrate MicroPython’s 13th Birthday!

And another video with a longer demo, this one shows how to make your quiet linear keys sound like an IBM Model F keyboard.
