For a reliable connection we'd recommend powering it directly off a LiPo battery using the on-board connector. Check the position of the jumpers by the aerial. If these are in the SWSerial position you'll need to use { rx: D7, tx : D8 }, otherwise if it's Xduino use { rx: ...

If you already connect the module with arduino like in picture above, then this is the time to test communication between module and arduino, to make sure that arduino can give command to SIM900A module. Don’t forget to double check the wiring connection. In this test, we will use AT ...

Arduino Connection The module has 3.3V TTL levels which means connecting its Rx pin directly to an Arduino’s Tx pin is a no-no. Here’s a diagram you can use to connect the breakout board to anArduino UNO: We can then use the same sketches we used in the SIM800L tutorial. ...
You don't need to wire up reset, and can instead just passundefinedinto therequire('SIM900').connectcall shown below. Once wired up, power is applied, and thePWRbutton is held down for 2 seconds a 'Network Connection' LED should flash every second to show that the SIM900 is trying to...
