Just Now SB Components has launched another creative stuff on Kickstarter, A first-ever Pico 2G expansion board ever made. 

Pico 2G Expansion is powered by the SIM868 quad-band GSM/GPRS module, which includes an onboard CH340 USB to UART converter, Voltage Level Translator with Auto-Direction Sensing and 15-kV ESD Protection, SMA and IPEX Antenna Connector that covers the 850/900/1800/1900MHz frequency band, and an onboard 1.14" LCD with auto multi-level repeating.

Because of its ease of installation, versatility, and high-quality user interface, the Raspberry Pi Pico 2G extension is the perfect choice for creators when building communication projects. SB Components created the Pico 2G extension to communicate with Quad-band GSM/GPRS + GNSS modules, which improves the product's quality of work.
