Product Description

1. Introduction
 

6221B-SRC support 1-stream 8021.ac solution with Mu-MIMO STA mode with Bluetooth

smart ready controller, SDIO1.1/2.0/3.0 interface, HS-UART mixed interface.

It combines WLAN MAC, a 1T1R WLAN baseband, RF in a single chip.

Module complies with IEEE 802.11 a/b/g/n/ac standard and the speed can achieve up to 433Mbps.

Module complies with bluetooth core specification V4.2. support dual mode (BR/EDR+low energy controllers).

for low energy, it supports mutiple states and allows active links in master mode and don't support scatternet topology.
