5G Module Series
RM520N-GL_Hardware_Design 19 / 84
2.3. Evaluation Board
To help you develop applications conveniently with the module, Quectel supplies an evaluation board
(5G-M2 EVB), a USB to RS-232 converter cable, a USB type-C cable, antennas, and other peripherals to
control or test the module. For more details, see document [2].
To meet this operating temperature range, you need to ensure effective thermal dissipation, for example, by adding
passive or active heatsinks, heat pipes, vapor chambers, etc. Within this range, the module can meet 3GPP specifications.
To meet this extended temperature range, you need to ensure effective thermal dissipation, for example, by adding
passive or active heatsinks, heat pipes, vapor chambers, etc. Within this range, the module remains the ability to establish
and maintain functions such as voice*, SMS, emergency call*, etc., without any unrecoverable malfunction. Radio spectrum
and radio network are not influenced, while one or more specifications, such as P
out
, may undergo a reduction in value,
exceeding the specified tolerances of 3GPP. When the temperature returns to the normal operating temperature level, the
module will meet 3GPP specifications again.
