These BOOT_MODE lines are referred to the VCC_SCU_1V8 power domain. By default, none of them
are configured inside the module. To configure the desired boot mode, they must be driven low or
high in the carrier board in the following way:
n
To set high level, place a 4.7K pull-up to VCC_SCU_1V8.
n
To set low level, place a 100K pull-down to GND.
Wireless interfaces
The ConnectCore 8X System-on-module combines a wireless local area network (WLAN) and
Bluetooth dual solution to support MIMO 2x2 IEEE802.11 a/b/g/n/ac WLAN standards and Bluetooth
5.0, enabling seamless integration of WLAN/Bluetooth and Low Energy technology.
WLAN IEEE 802.11a/b/g/n/ac
The 2.4 GHz band on the ConnectCore 8X module supports 20/40 MHz bandwidths, and the 5 GHz
band supports 20/40/80 MHz bandwidths. The following sections specify the performance of the WLAN
IEEE 802.11a/b/g/n/ac interface on the ConnectCore 8X module.
