The shielding case is connected to GND in the module. For mounting the module, when pattern wiring that touches the shielding case is carried out on the product board, do not cause a short-circuit between the shielding case and the pattern. For example, apply resist on the entire surface that touches the shielding case. 2. The effects of noise on a product board depend on the connection of GND/NC to the fixation pads. Select the connection with better electrical characteristics in the module mounted state. CAUTIONS IN USE This module consists of precision electronic components.
