Description:
The DX-BT20 module is a low-power Bluetooth 5.0 BLE (Bluetooth Low Energy) serial module, with high transmission and reception sensitivity, small size and low cost.
It offers the possibility to easily connect to a micro controller, such as PIC, Atmel and then development kits such as Arduino, using 2 serial Tx and Rx pins, UART (TTL), and interact with the sketch using AT commands. The small size also allows you to easily place the Wi-Fi module within more complex projects.
The SMD format allows the module to be soldered directly to the PCB of your project.
