Pico 2G Expansion (Incomplete Wiki)
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.
