1 Product Overview
1.1 Introduction
The CSM92F30 Module is a highly integrated Bluetooth 5.0 low energy SOC module. It has 32-bit
ARM® Cortex™-M0 CPU with 512KB Flash, 138KB SRAM and an ultra-low power, high performance,
multi-mode radio. It intergrate rich feature peripheral units, programmable protocol and profile to support
BLE application, enables customer product to be built with minimum bill-of-material (BOM) cost.
