Wow! So apparently FutureProofHomes has also announced his ”Satellite1 PCB Dev Kit” also sound to use same or similar XMOS chip in combination with an ESP32-S3 module but he has designed as a two-board PCBs voice satellite hardware development kit:

Satellite1 PCB Dev Kit

The Satellite1 PCB Dev Kit contains the two PCBs necessary to build your own completely private voice assistant & multi-sensor with XMOS advanced audio processing & music playback. Add your own speaker and power supplies.

Satellite1 HAT Board:

This board features 4 PDM microphones, 12 NeoPixel LEDs, humidity/temp/lux sensors, 4 buttons (volume up/down, action button & hardware mute), plus the XMOS audio processing chip and a power DAC with for amplified speaker-out connection or 3.5mm headphone connection. All remaining GPIOs are also exposed.

The Satellite1 Hat connects easily to the Sat1 Core Board but can also be paired with a Raspberry Pi or a PC/Mac via USB! Perfect for all your voice assistant and audio projects!

Satellite1 Core Board:

The Satellite1 Core Board contains the ESP32-S3 n16r8, USB-C Power Delivery and 40-pin connection. This board attaches to the companion Sat1 HAT Board.

Looks like he also posted a future roadmap showing that he working on a a nice enclosure (as well as the mentioning of an optional recessed enclosure for in-cealing / in-wall mounting of this smart speaker):

And yeah, I noticed now that FutureProofHomes had posted a preview video on YouTube showing of an early prototype version devkit of that 4-months ago when he at the time called that project “HomeX” (but at that time he had based the prototype on the wyoming-satellite platform running on a Raspberry Pi instead of using Nabu Casa’s upcoming ESPHome-based voice-kit hardware platform that runs on ESP32-S3 and using an XMOS xCORE chip for audio processing):

PS: The new design reminds me of the “Onju Voice” PCB replacement for the Google Nest Mini (2nd gen), which is a open-source hardware project that I hope someone else will pick up and update now:
