the bwn driver [1] supports PCI and CardBus devices only. BCM4330 is an
SDIO adapter [4]. It doesn't work for me in FreeBSD 11.0 either [2].
Just for the record, Linux brcmfmac (Dual BSD/GPL) works with this
adapter [3] in 2.4GHz (Uncomplete list of 5Ghz channels is reported,
but don't work for me).

Cheers,
Vladimir

The Broadcom BCM4330 single chip device provides the highest level of
integration for a mobile or handheld wireless system, with integrated
IEEE 802.11 a/b/g and single-stream 802.11 n (MAC/baseband/radio),
Bluetooth 4.0+HS, and FM radio receiver and transmitter. It includes
on-chip 2.4GHz and 5 GHz WLAN power amplifiers that meet the output
power requirements for most handheld systems while permitting and an
optional external power amplifier for higher output power applications,
if required.
