Introduction

The WS2118-00 series is a sub-1GHz and Bluetooth low energy ultralow power wireless MCU module. This module is built-in ST S2-LP and BlueNRG-1 chip. The module is a cost-effective, high performance, ultra-low power, sub-1GHz and Bluetooth low energy RF devices. Very low active RF and MCU current and low-power mode current consumption provide excellent battery lifetime and allow for operation on small coin cell batteries and in energy-harvesting applications.
