E73-2G4M08S1B Bluetooth Module

Description:
Bluetooth is a wireless technology standard used for exchanging data between fixed and mobile devices over short distances using short-wavelength UHF radio waves in the industrial, scientific and medical radio bands, from 2.400 to 2.485 GHz, and building personal area networks.
Every Bluetooth device has one or more profiles installed. These profiles determine what the device is capable of, such as "Hands-Free" (mobile headsets) or "Human Interface Device" (computer mouse).
E73-2G4M08S1B is a wireless Bluetooth module witch features small size, low power consumption. It adopts the originally imported RFIC nRF52840 of NORDIC, supporting BLE 4.2 and BLE 5.0. The chip has high-performance ARM CORTEX-M4F kernel and other peripheral resources, such as UART, I2C, SPI, ADC, DMA, PWM, etc.
The operating range is based on the device class.
