Product Information
BT18/18-A/18LE/18LE-A Dual-mode wireless Bluetooth module
Model Number：M2021025:BT18/18-A/18LE/18LE-A
BT18 series Bluetooth module, BLE4.2+EDR3.0, dual-mode wireless serial port transparent transmission, high cost performance, SOC system, equipped with professional RF shielding cover, effectively shield the external electromagnetic wave on the internal circuit, better performance, a variety of styles optional. The performance of the baseboard module is the same as that of the patch module. The baseboard module supports the TTL level voltage of 3.3-6V and can be directly connected to most of the 5V microcontrollers.SPP2.0 Classic Bluetooth +BLE4.2 Bluetooth protocol, dual mode, can connect mobile phones and computers
