The TPS Online Configurator can help you decide which parts to use in conjunction
with Tibbit #45. The Online Configurator lists the Tibbit as consuming 500mA of
current, which we found to be a good approximation of the current burden it places
on a power source, but does not take into account the current spikes or that the
Tibbit often operates with lower power consumption.
Operating temperature
In testing, this Tibbit operated normally in the industrial temperature range (-40°C
to 85°C). However, SIMCom recommends an operating temperature range for the
modem of between -30°C and 80°C and warns of reduced performance when
approaching either extreme of the industrial temperature range.
In addition to the temperature constraints on the module, there are also limitations
for off-the-shelf SIM cards. While regular consumer SIM cards are certified to
operate in a temperature range of -25°C to 85°C, industrial/automotive SIM cards
can operate at between -40°C and 85°C, with some capable of operating at
temperatures of up to 105°C. In internal testing, some consumer SIM cards
deformed at low temperatures and became nonfunctional.
We highly recommend that you assess your application's projected environmental
conditions and choose an appropriate SIM card.
Library Support
The CELL software library (see the TIDE, TiOS, Tibbo BASIC, and Tibbo C Manual)
unlocks the full capabilities of this Tibbit and can be easily included in your project
through Cody, our project setup wizard. Cody examines your TPS configuration to
create sample code that you can use as the foundation for your project.
The CELL library handles modem initialization, PPP connection establishment and PPP
data communications.
Tibbit variations
This Tibbit is supplied in three regional variants as detailed in the table below:
1. While SIMCom identifies a few specific countries or regions for each variant of
the SIM7500 family of modems, we have omitted them because they are not fully
inclusive lists. What is important is that you select the version most compatible
with the bands in use in your region (and compliant with your local regulations).
