Sim800l Arduino Wiring Diagram. This would be helpful in troubleshooting your SIM800L-based project. Thus connecting the D2 pin to the SIM800Ls RING pin above the DTR pin if its not visible in yours is a must.
Here I made a simple setup where I was able to display the signal level and the network status on an LCD. The version 2 has 5V pin enabled for power that make this module Skip to content. Thus connecting the D2 pin to the SIM800Ls RING pin above the DTR pin if its not visible in yours is a must.
Arduino and SIM800L wiring diagramConnect your arduino and SIM800L like above.
Because a 33v from SIM800L can be able to handle by a 5V Arduino Pin TX probably a lesser voltage but it takes even a 27v as a high signal. Here I made a simple setup where I was able to display the signal level and the network status on an LCD. We will set it up with Arduino and send simple text messages.
