It includes the wireless code.

I think you're confusing this with WiFi. The Nordic Semiconductor chips don't require a firmware upload; the protocol they run is vastly simpler than wifi -- it's like UART-over-2.4ghz-GFSK-radio plus some error correction.

The block diagram doesn't show any kind of CPU in there.

Oh of course, I'm confusing it with Bluetooth boards which need a hefty wireless firmware stack. Boards using a dongle don't necessarily need that complexity.
Yeah the NuPhy Air is the first wireless keyboard I've ever been willing to use, specifically because it is non-bluetooth (and I can recompile the firmware to guarantee that it isn't using bluetooth!)

Bluetooth keyboards were a horrible idea.
