Looks like it only has 6 discrete components [0], and the pinout on the MCU looks like a standard QFP [1] (and everything else is on larger pads), so I think that you should be able to manufacture this using standard production techniques/manufacturers. But I know hardly anything about hardware, so I may be completely wrong here.

Pedantic correction: it's a QFN (quad flat no-leads) package, as it doesn't have any legs. Agreed though, this is well within normal capabilities.
