Power Pins
Below table shows WE310F5 needs 3.3V DC regulated supply supporting 500mA peak
current.
Table 7: Power Pins
We recommend adding an external EMI filter to improve the quality of the power supply
especially when the module is embedded with other technologies, (i.e. Cellular). The
pigreca filter composed by ferrite bead and 10pF capacitors (C2,C3) is used to provide an
high impedance value for high frequency signals, while the 100uF and 22uFcapacitors
(C1,C5 and C4) are used to bypass low frequencies from switching regulator circuit and
to provide a supply tank for high current absorption.
