Description
Overview
The module BC101HZ-22P is a highly integrated single-chip Wi-Fi 802.11n and Bluetooth Low Energy (LE) 5.2 combo solution designed for applications that require low power and compact size. Integrating a powerful 32-bit MCU and a comprehensive set of peripherals and interfaces makes the module ideal for advanced Internet of Things (IoT) applications. It is based on the Beken BK7238 chipset, which gives it the advantage of the open-source SDK.
Using advanced design techniques and process technology, the module delivers high integration and minimal power consumption in an extremely small package for smart lighting, smart homes, indoor positioning, and other complex IoT applications. This vertical mount is suitable for applications like smart sockets where fewer IO pins are required and there is a space constraint.
SDK is based on a Linux development environment, available with sample codes for the development.
