Overview

---

BK7252 is a 2.4 GHz 802.11n and Bluetooth LE 4.2 combo chip with audio peripherals and image sensor interface. It integrates hardware and

software components to finish a complete 802.11b/g/n audio and video application, which supports AP and STA role simultaneously, and integrates Bluetooth low energy transceiver and version 5.0 complaint protocol stack. The high speed 32-bit MCU and large embedded RAM make it able to support multiple cloud links and also suitable for audio and image applications.
