Is it possible to run Android OS on the Compute Module?
There are currently some experimental builds of Android for the Raspberry Pi; however, these are
probably not stable enough to be used for professional and commercial applications and may not even
work on the Compute Module version of the Raspberry Pi.
Does the Compute Module 4 provide support for Wi-Fi or Bluetooth?
Versions of the Compute Module with built-in wireless functionality together with the DS1-IF21CE
interface board can be used to provide Wi-Fi using an external antenna. At the time of writing the
Bluetooth function is disabled by the Interface Board pending regulatory approvals.
