I was surprised with it's ability to receive FM radio broadcast without any problem in such a small module. The size is not bigger than a coin, really small. It may a bit difficult for wiring but it can be done. You can also add small power audio amplifier and use small speaker directly. Here is the module chip, small power amplifier in prototyping pcb.
This module is very useful if you want to create project with time related data such as data logging, alarm and clock. This module keep track the time even the system has been turned off. Thanks to small coin battery installed on this module. Once it has been set, module will keep track the time as long as battery is still life.
