I'm working on a bluetooth music player project for my motorbike helmet to play music on the go, and I'm using the CSR8645 BLE module. For low power applications such as small speakers/earphones, would I need an external amplifier to amplify the signal from the SPK_L and SPK_R lines? Or is the signal from the chip strong enough to power the speakers?
Theres not much documentation on this chipset, apart from this website i found below.
