The Raspberry Pi Pico 4G Expansion is a Quectel EG25-G module-based 4G Expansion board that includes an LTE category 4 module, built-in WiFi, multi-constellation GNSS, USB 2.0 High Speed Interface.

Pico 4G Expansion supports maximum downlink rates of 150Mbps and uplink rates of 50Mbps over LTE, while backward compatibility with current 2G networks guarantees connectivity even in places where 3G or 4G coverage is not available.

Pico 4G Expansion also includes a 1.14-inch display with a resolution of 240 x 135 pixels, 65K RGB colours, 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. Specifications:
