4. LAYOUT AND MOUTING GUIDELINES
 We recommend 2 or more layers for the Carrier Board (Host PCB). The top side shall be mostly ground.
Signal routing shall be done in the bottom or middle layers.
 When laying out the Carrier board for the MESHTEK-H52E module, the areas under the antenna and
shielding connections should not have signal traces, ground planes or exposed vias.
 For the best Bluetooth range performance, the antenna area of module shall extend 6.3mm outside
the edge of Carrier Board or 6.3mm outside the edge of a ground plane.
 For the best Bluetooth range performance, keep all external metal away from the antenna area.
