CYBT-213043-02 is fully integrated and certified ready to use solution that provides all necessary components required to operate Bluetooth communication standards.
- I would suggest you to check the "Connections and Optional External Components" section in the datasheet to know about the required connections when using the module. https://www.cypress.com/documentation/datasheets/cybt-213043-02-ez-bt-module
- And also, check the CYBT-213043-MESH EZ-BT™ Module Mesh Evaluation Kit schematics and hardware files. https://www.cypress.com/documentation/development-kitsboards/cybt-213043-mesh-ez-bt-module-mesh-evaluation-kit
Yes, you will be getting a module as shown in the image.
Yes, you need use USB to Serial converter. Please check the module evaluation kit schematics given above.
The CYBT-213043-02 includes connections for an external 32-kHz oscillator to provide accurate timing during low power operations.
Note that, a 24.000 MHz, 12PF (Y1) crystal is a critical component used in the CYBT-213043-02 module. (Check page 12, 13).
Thank you for the answer, I am following your recommendation of the document and found the external components required just like in the picture below.
But what I dont understand next is "critical component", does it mean that I have to add it as external component later on ? or ... its already in the module ? because I cant find the pin to connect to that 24.000 MHz xtal.

"Critical Components" are the main components used in the CYBT-213043-02 module. These components are already present inside the module.
