Declaration of conformity for t862 models difference 1.Infrared module differences The two models differ in infrared imaging resolution: t862- 1 features 160×120 resolution, while t862- 2 is 256×192, resulting in different infrared thermal imaging modules being adopted. 2. Data Interface Differences The t862- 1 infrared thermal imaging module uses the DVP data interface, whereas the t862- 2 module uses MIPI. The common system CPU for both models supports MIPI but lacks a DVP interface. Accordingly, t862- 1 incorporates a DVP to MIPI conversion chip, whose circuit design provides the required clock and power supplies for chip operation. See the comparison in the figure below. Owingtotheinherentpropertiesoft862- 1’s infraredthermalimagingmodule,anextraoperatingcrystaloscillatoris required.Thereforet862- 1featuresanadditional27 MHzcrystaloscillatorcomparedwith t862- 2.
