m1805 Module Specification

The upper and below area of antenna (including the case) shall have 4mm or more than 4mm

clearance to reduce the influences for antenna.

*The Grey area above is Carrier board.

7.3 Installation and soldering

(1) Please do not lay copper under the module antenna. It can prevent the influence of signal

radiation and the transmission distance from being affected.

7.4 Handling and storage

(1) Due to the fact that CMOS components are included in the module, it is better to eliminate

static electricity at any methods when transporting or working with the module. Moreover, it is

strongly recommended adding anti-ESD components to circuit design to hinder damage from

real-life ESD events. Anti-ESD methods can be also used in mechanical design.
