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.

Features

  • 1.14” LCD
  • Low Power Consumption

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.
    • Lcd1_14driver.py : This library is of lcd 1.14 inch
  • To make a call, you need to uncomment this line Call = SIM868.call(Mobile_number,10) in pico_2g_exp.py file
  • To make a message, you need to uncomment this line Message = SIM868.message(Mobile_number,Write_message) in pico_2g_exp.py file
  • To turn on GPS, you need to uncomment this line Gps = SIM868.gps() in pico_2g_exp.py file
  • To scan Bluetooth devices, you need to uncomment this line Bluetooth = SIM868.bluetooth() in pico_2g_exp.py file

You need to enter your mobile number in the code pico_2g_exp.py to make call and send the message

  • Please follow the Resources to run 1.14' LCD
