Confirm the approved input-voltage lower limit: the supplied PDF states 6–32 V in its power section and 7–32 V in its pin table. The official overview and specification table also differ on weight. Communication-current figures do not establish continuous-transmission power consumption. Firmware, regional bands and management-platform scope must be confirmed for the ordered configuration.
