①
The connection to the antenna must be a 50Ω characteristic impedance.
②
The antenna matching circuit parameters can optimized by users, based on the
user’s circuit board. Resistor R1/R2/R3/R4 is 0Ω by default and C1/C2/C3/C4 is
empty by default.
③
To prevent electrostatic damage to the module’s components, it is suggested that
choosing a low capacitance ESD device PESD0542U015 to stick on the D1/D2 of the
antenna connection.
