Is there a Banana Pi board that can use Raspberry Pi 3 accessories? I bought an Raspberry 3 ages ago but they keep biting the dust just to a known fault in the board. Therefore I was wondering if there was as an alternative board such as a BananaPi.
Your description is still very non-specific. If it is just DC fans without PWM and speed detection, you could hook them up onto any +5V power headers. I am only interested in the Banana Pi routers so at least RPI 2 pro if not all models have +5V and GND power headers.
BPI-R2 Pro is more like a server with more than needed Ethernet ports.
But regardless, you could go to BPi’s product page and find one that supports Mini CSI, that’s the sole requirement for using your camera.
