4.2 Operating conditions
☞ Unless otherwise indicated, all operating condition specifications are at an ambient temperature
of +25 °C.
⚠ Operation beyond the operating conditions is not recommended and extended exposure beyond
them may affect device reliability.

RF performance may be affected when the input voltage at VCC is outside the herein stated normal operating range limits,
though the module is still fully functional when the input voltage at VCC is inside the extended operating range limits.
18
Range defined for the VCC pin #51 (supply input for internal baseband Power Management Unit and transceiver) of LARA-R211
modules, and for all the VCC pins of the other LARA-R2 series modules, and. Input voltage at the related VCC pins must be
above the herein stated extended operating range minimum limit to switch on the LARA-R2 series modules. The LARA-R2
series modules may switch off when the input voltage at the related VCC pins drops below the herein stated extended
operating range minimum limit.
19
Range defined for the VCC pins #52 and #53 (supply input for the internal power amplifier) of LARA-R211 modules.
