What's the BOM look like? I'd love to understand more about the design. The software's open source, right? After a brief skim I didn't see a repo link. Does anyone know where the source is? Do they use an AI accelerator DSP/TPU or just plain-old-software-on-a-CPU?
Regarding the BOM, I assume you mean the Mark II? That you can find here: https://github.com/MycroftAI/hardware-mycroft-mark-II/tree/m... We actually ended up designing our own RPi daughterboard called the SJ201. It's mostly an audio front end with an XMOS XVF-3510 and dual mics, but also includes a 23W amp, some LEDs for feedback, buttons, a hardware mic switch, GPIO breakout and power management (amongst other things).
