Is there a board that comes with the Drop-in replacement for Raspberry Pi camera V2 with the module from the beginning, rather than a replacement?
Or is there a Raspberry Pi camera V2 baseboard equivalent for sale?
No, because the Raspberry Pi does not allow an IMX219 camera baseboard from anyone else, so you must have an official one to use any replacement. You can read more about why we’d build this replacement and how it works on our blog here: https://www.arducam.com/raspberry-pi-camera-v2-m12-autofocus-lens-spy-cam/
