- Integration: The ESP32 T-Call V1.3 integrates both the ESP32 microcontroller and the SIM800L GSM module, making it a more compact and convenient option. On the other hand, using a standalone SIM800L module requires an additional microcontroller or development board to control it.
- Pins and GPIOs: The ESP32 T-Call V1.3 has more GPIO pins and interfaces available than the standalone SIM800L module. This makes it more versatile for use in different applications.
- Power consumption: The ESP32 T-Call V1.3 has a lower power consumption than a standalone SIM800L module with an MCU since it has an integrated microcontroller and optimized power management features.
- Software support: The ESP32 T-Call V1.3 has good software support, with libraries and examples available for use with the Arduino IDE and other development environments. The standalone SIM800L module also has software support but may require more effort to set up and integrate with a microcontroller.
- Price: The ESP32 T-Call V1.3 is more expensive than a standalone SIM800L module, but considering the integrated ESP32 microcontroller, the cost may be justified in some applications.
The ESP32 T-Call V1.3 module offers a more integrated and versatile solution for cellular communication with the GSM network while using a standalone SIM800L module with a microcontroller provides a more cost-effective option with more control over the hardware. The choice between the two depends on the specific requirements of the application.
