Pico 2G Expansion

Raspberry Pi Pico 2G Expansion is a QUAD-Band GSM/GPRS/GNSS Expansion designed dedicatedly for Raspberry Pi Pico with UART, USB 2.0 Interface, 850/900/1800/1900 MHz, Bluetooth 3.0 based on SIM868 module to perform easy and efficient communication. Pico 2G Expansion works on the embedded TCP/UDP Protocols with Multi-constellation GNSS receiver support.

Pico 2G Expansion also includes a 1.14-inch display with a resolution of 240 x 135 pixels, 65K RGB colors, and a sharp and vivid exhibiting effect, designed primarily for user engagement via SPI connection by incorporating a GPIO header. The 1.14-inch LCD includes the ST7789 Driver and SPI Interface, decreasing the amount of IO pins required.

Installation

USB to SIM868 Communication

  • Connect Selection jumpers for USB to SIM868 communication mode.
  • Insert SIM card on SIM card slot, and connect GSM and GSM Antenna on antenna connector.
  • Connect USB on the USB port of Pico 2G GSM board.
  • Press and hold PWR_KEY to turn on the GSM module (SIM868) and release it once STATUS led turned on.
  • Now open any Serial terminal app on (Windows or Linux), Set com port of Pico 2G expansion and baud rate to 9600.
  • Now you can send AT commands from the terminal to control your SIM868 Module.

MicroPython

  • Connect Pico on Pico 2G Expansion.
  • Connect jumper in SIM868 to Pico Communication mode.
  • Connect GSM and GPS antenna on Antenna connectors.
  • Insert 2G enabled SIM card on sim card port.
  • Download or clone the repository of Pico 2G expansion from the below link.

https://github.com/sbcshop/Pico-2G-Expansion

  • Now open the below examples code as per their function to test the pico 2G Expansion in Thonny Ide.
    • SIM868.py: This file contain the library of the module, you need to add this file to pico.
    • pico_2g_exp.py: This is the main file that you need to run.


  • To make a call, you need to uncomment this line Call = SIM868.call(Mobile_number,10) in pico_2g_exp.pyfile
  • To make a message, you need to uncomment this line Message = SIM868.message(Mobile_number,Write_message) in pico_2g_exp.pyfile
  • To turn on GPS, you need to uncomment this line Gps = SIM868.gps() in pico_2g_exp.pyfile
  • To scan Bluetooth devices, you need to uncomment this line #Bluetooth = SIM868.bluetooth() in pico_2g_exp.pyfile

file in thonny ide and enter your mobile number from 123456 to the actual number at the end of this code, and timeout to release the code after specified seconds (i.e: 15 seconds in the default case).
