Bluetooth® Low Energy Wireless MCU Module

The certified WB2072-00 module from JORJIN is a wireless MCU module targeting Bluetooth 5.2 low energy applications. This module is based on ST BlueNRG-355AC wireless MCU QFN-32 package chip. The module is a cost-effective, ultralow power, 2.4-GHz 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.
