Arduino Compatibility:Effortless integration with Arduino boards via TTL serial port, no MAX232 required. Mini Size:Nano-sized SIM card slot and compact design for space-saving projects. Automatic Boot:Effortless power-up with automatic homing network feature. ...
However, it is almost impossible to find satisfactory explanations about its use and especially about its connection. So in this tutorial we’ll see how to plug in and power a SIM800L from a Raspberry (note that it also works for an Arduino), without external power or battery! The hardwar...
Failed connection or no data received The first connection with a new SIM card, a new module, or at a new location/tower may take aLONGtime - up to 15 minutes or even more, especially if the signal quality isn't excellent. If it is your first connection, you may need to adjust your...
This project shows how to connect the TTGO T-Call ESP32 SIM800L board to the Internet using a SIM card data plan and publish data to the cloud without using Wi-Fi. We’ll program this board with Arduino IDE.Watch the Video Tutorial...
