1 Introduction
Sky Jiarun Technologies
introduces the pioneer of the Bluetooth
5.3 modules SJR-BTM356 which is a high performance, cost effective, low power
and compact solution. The Bluetooth module provides a complete 2.4GHz
Bluetooth system based on the QCC3056 WLCSP chipset which is a single
chip radio and baseband IC for Bluetooth 2.4GHz systems. This module is fully
qualified single-chip dual mode Bluetooth@v5.3 system.
