![]() ![]() Connect the SIM800L VDD to a GPIO providing power on the Raspberry.In theory, to use a SIM800L with the Raspberry Pi you must therefore do like this: For example, sending an SMS, entering a PIN, checking the status of the network, and much more! In order to control the SIM800L, from the Raspberry, you will have to provide power to the first and physically and softwareally connect both using a TTL port, more often called a port or serial interface.įrom there you can control the SIM800L by sending hayes commands to the series port – in fact more often REFERRED to as AT commands – which are commands specific to the functions of a modem. Overall it behaves like a phone that you could control directly from your Raspberry. It is the one who registers with your operator’s network, etc. Theory, how to use a SIM800L with a Raspberry Pi? No time or desire to read the explanations? Go directly to the “In Practice…” part. Now let’s move on to explanations and practice. If yours is a smaller size (nano), you will need an adapter. Note that the SIM card must be in micro s im format. ![]() Of course, you’ll also need a Raspberry with raspbian installed and a SIM card with a subscription. So I think the easiest thing is to take a n electronics kit like this that contains everything we just mentioned.Ī kit like this contains everything you’ll need. You could buy each item alone, but you should actually buy dozens of capacitors and diodes just to pay off the shipping costs. A breadboard, a capacitor 5 V, 100♟ or more, a 1N4007 diode, Dupont cables.A soldering iron to assemble your SIM800L if it is not already.We will go into the details and explanations later in this tutorial, but be aware that to link a SIM800L to a Raspberry a little hardware is needed. 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), w ithout external power or battery! The hardware needed to connect your SIM800L to your Raspberry. However, it is almost impossible to find satisfactory explanations about its use and especially about its connection. It’s an affordable way to send SMS with a Raspberry Pi or Arduino, connect in 3G or implement a GPS. The SIM800L is a GSM/GPRS modem that is widely used in electronics due to its very low price and wide availability. We apologize for any errors this may cause.
