@atulkatti we offer to our customers the complete Altium projects of all the carrier boards and evaluation boards we designed to work with our modules. These projects can be downloaded from our developer website:
On the same website, you can find the Colibri and Apalis design guides as well as a really detailed layout design guide:
These guides are generic, so I am not sure you can find detailed information about the scenarios you are planning to implement. Nevertheless, I am sure this material can be really useful and a good starting point for your design.
We also provide a powerful tool, the pinout designer, which will help you to explore and select the interface available on our modules. This tool will also allow you to check the compatibility across modules belonging to the same family to design a carrier board which can be easily upgraded in the future if the next application requires, for example, a different module with higher performances.
Regarding the software, you can find several useful threads in this community or also on our developer website, in the software section:
