1. Function Description
The transmission module is based on Bluetooth 5.0 protocol standard, the working frequency band is 2.4 GHZ range, the modulation mode is GFSK, the maximum transmission power is 4 db, the maximum transmission distance is 60 meters, and the low power chip is used.
Bluetooth module can realize module and mobile phone data transmission, default without configuration can quickly use BLE Bluetooth for product applications.
Fast and convenient for BLE application
