Quectel BC66 - Pin Assignment

NB-IoT Module Series
BC66 Hardware Design
BC66_Hardware_Design 11 / 59
1.
1)
Within operation temperature range, the module is 3GPP compliant.
2.
2)
Within extended temperature range, the module remains the ability to establish and maintain
functions such as SMS* and data transmission, without any unrecoverable malfunction. Radio
spectrum and radio network will not be influenced, while one or more specifications, such as Pout,
may exceed the specified tolerances of 3GPP. When the temperature returns to the normal operation
temperature levels, the module will meet 3GPP specifications again.
3. "*" means under development.
