LoRaWAN Module MKL62BA 4.2 Main PCB Layout And Module Mounting Recommended for main board layout: - Avoid running any signal line below module whenever possible. - No ground plane below antenna. - If possible, cut-off the portion of main board below antenna. Recommended module mounting: You can refer to the following references for the mounting design of the module with on-board ceramic BLE antenna. For external LoRa antenna to the u.
LoRaWAN Module MKL62BA - Ground plane shall be at least 6.5 mm from the edge of the antenna area of module. - All module GND pins MUST be connected to main board GND. Place GND vias close to module GND pads as possible. Unused PCB area on surface layer can flooded with copper but place GND via regularly to connect copper flood to inner GND plane. If GND flood copper underside the module then connects with GND vias to inner GND plane.
