Bluetooth low energy (LE) Module BT01-2 is a Bluetooth low energy controller CC2541. This module is ideal for low power wireless sensing device applications including mobile phone accessories, sports, consumer electronics, HID and etc. The module is integrated with PCB antenna and crystal to reduce the external BOM Cost. We also provide EVK-CC2541 Development Kit for engineer to develop their own application based on our BT01-2 Bluetooth module.
