Are the GPIO Pins open for usage?
I want to use this for a future project one day, but I hope the pins are still usable with this board...

Can I use GSM board with UPS PIco Advanced?
Can I use Itead Raspberry Pi GSM Board (SIM800) with UPS PIco Advanced - Uninterruptible Power Supply (HV3.0B+) at same time?
  • You can! If running on PIco battery you will probably experience low power warnings if making a phone call due to the heavy power consumption a phone call makes :)

Can I place phone call with this? Is the RPI3 powerful enough to supply power or should we use an external power cord?

Wil this work with RPi Zero W
Is it possible to connect the RX, TX and GND pins to the UART pins on the Pi Zero W? Will it work on disabling the console on the RPi Zero W
  • Yes it should be possible, however you may need to power the GSM board with a seperate 5v power supply as the Pi Zero might not be able to provide enough current. The GSM board can draw up to 2A on load.

Would it fit on an RPi Zero?

Please Note. This item is being discontinued. We now stock our own Raspberry Pi GSM board here!

Connect your Pi to the world's mobile networks! The Raspberry Pi GSM Add-on V2.0 from Itead is a customized SIM800 quad-band GSM/GPRS/BT module for use on the Raspberry Pi. This GSM module is plug and play, and can be accessed via UART for GSM mobile network access. We have designed a case for the Itead GSM Board and Raspberry Pi here!

AT commands can be sent via the serial port on Raspberry Pi, thus functions such as dialing and answering calls, sending and receiving messages and surfing on line can be realized. The module supports powering-on and resetting via software, and also features a micro-USB power input, which can be used to power both the Raspberry Pi, and the GSM board at the same time.

This package includes both fixed and flexible SMA antennas.
