7.13.1 Description
The STM32MP157C-DK2 Discovery kit support Wi‑Fi
®
802.11b/g/n and Bluetooth
®
Low Energy (BLE) V4.1.
These functions are supported with the LBEE5KL1DX-883 MURATA module. This module is driven by a SDIO for
the Wi‑Fi
®
interface, and a USART for the Bluetooth
®
. The PCM format is used for audio data.
7.13.2 Operating voltage
The LBEE5KL1DX-883 module supports the 3.3 V voltage range.
