Connect sim800 to Raspberry PI (RX, TX) Ask Question Asked4 years, 3 months ago Active11 months ago Viewed10k times 5 1 I’ve been trying to connect my sim800L to my Raspberry pi 3 model B (rasbian) but without success…
Can a SIM be connected to a pi ground?
The circuit as shown will not work as there is no common voltage reference between the SIM and the Pi. You need to connect a Pi ground to either the SIM ground or to the battery ground (-ve terminal).

Can a Raspberry Pi be used as a 3G modem?
We are using Raspberry PI GSM Add-on V2.0 from itead as out 3g modem. Connecting it to the raspberry was quite easy as it is designed to sit on top of the rpi like a hat or a shield as show on the picture bellow
What kind of pin is used on Raspberry Pi 3?
TX pin is used to transmit the serial data and RX pin is used to receive serial data coming from a different serial device. To download the Raspberry Pi 3 Model B+ Schematic , click here. You can control the GPIO of Raspberry Pi 3 B+ using many programming languages.
What does GPIO stand for on a Raspberry Pi?
GPIO stands for General Purpose Input Output pins these pins are used to connect the Raspberry pi board to external input/output devices. Like the previous model, model B+ also consists of a 40-pin GPIO.
Where are the GPIO pins on a Raspberry Pi?
The GPIO pins on the RPI slide into the socket under the add-on and the pins on top of the add-on now function as the GPIO pins for the RPI. As seen in the picture we could connect our PIR sensor to the pins on top of the add-on. Once the add-on was in place raspberry was powered on the pwr led on top of the add-on lit up.
What kind of current does sim800 use?
SIM800 can consume up to 2A during transmission, and your RPi doesn’t have extra 2A lying around. Even if your power supply can provide 4.5A, your USB cable, micro USB plug and the over current protection circuit or the RPi are not designed to cope with such currents.
Can a GPIO connect to a Raspberry Pi?
