Most of these details are on the site, but the processor is a 6 Core Cortex A72 ARM running at 2GHz. Yes OS is running kernel 5.9, and is an ubuntu flavor. Wifi is a dual band AC chip, so should work with any setup you have.
The mostly blue SBC board model on the site looks awfully lot like an
Orange Pi 4. If it is, does it come with the onboard microphone still attached?
