BTM544 Bluetooth audio module，with Qualcomm QCC5144 chip,built in 32M FLASH.
Warm Reminder：
1. The module foot position is relatively dense, so a good welding machine foundation is needed. The module is tested before delivery and will not be returned after tin loading!
2. Bluetooth datasheet and schematic diagram. can be offered.
3. The actual pin pin pin corresponding to the PIO port needs to check the datasheet by yourself!
Sample quantity is limited, Delivery after 100% test (burn a test firmware)!
