The MLX90640 is a 768-pixel (32 x 24), low-cost thermal camera. It uses an array of infrared detectors (and filters) to detect the radiation given off by nearby objects by taking advantage of Planck’s radiation law. The MLX90640 is most notable because of its easy-to-use Python libraries that allow it to be read by Raspberry Pi computers. The MLX90640 can be used to map and record high-resolution temperature maps at refresh rates of up to 64 times per second (64Hz).

NOTE: There are two versions here, 1. an unsoldered board that needs to be soldered to be wired properly; and 2. a version that has a breakout connector that can be connected directly to a Raspberry Pi via the JST Dupont connector.
