To be determined
-30° to +70° C (FCC certified operating temperature range is -30° to +50° C )
-40° to +85° C
20% to 90% (non-condensing)
5VDC
Typical: To be determined (minimum 400mA)
Maximum Peak Current 2.0A
(Note: The VCC supply does not have to provide a constant high current
but must accommodate the short current spikes of about 1154µs every
4.651ms.)
Antenna: UFL button-type with maximum cable length of TBD" (TBD cm)
SIM: Standard 1.8V and 3V SIM receptacle
VCC/GND: Extra connector for retrofit situations in case VCC pin is not provided
with enough current (must be same 5V source as VCC pin) and cable length must
not cause more than TBD volts drop.
FTP client, ICMP, POP3 (receive mail), HTTP, SMTP (send mail), TCP/UDP
socket:
To be determined at a later date.
