Antenna can't be shieldedby any meal enclosure; All cover, include plastic, shall away from

antenna at least 10mm;

High-Flying suggest module better locate in following region at customer board, which to reduce the

effect to antenna and wireless signal, and better consult High-Flying technical people when you

structure your module placement and PCB layout.

High-Flying provides the EVK to promote user to familiar the product and develop the detailed

application. The evaluation kit shown as below, user can connect to module with the RS-232 UART,
