More specifically, the sensor is a Sony IMX477, slightly better than the IMX377 featured in the Nexus 6P, Nexus 5X, HTC 10, and Mavic Pro drone.
Pretty nice, for $50 in a neat little package. This kind of thing is usually a good bit more expensive.
Would be nice if they would use something similar to a Sony IMX327/290 for their next NoIR camera. That particular set of Sony sensors (STARVIS) would be much better for low light than their existing lineup.
