IoTFi 2G All-in-one RP2040 IoT Board with WiFi, GSM, GPS & LCD

The IoTFi is a powerful, all-in-one IoT development board built around the versatile RP2040 microcontroller. It uniquely combines 2G GSM connectivity with WiFi and Bluetooth, providing robust, multi-network options for remote data communication and control projects.

Its standout feature is the integrated SIM868 Quad-band GSM/GPRS module, complete with a micro SIM card slot. This module supports embedded TCP/UDP protocols, enabling reliable cellular data transmission. Complementing this is an ESP32 module, delivering dual-band WiFi and Bluetooth connectivity for local network and device interfacing.

For location-based applications, the board includes a multi-constellation GNSS receiver supporting both GPS and GLONASS satellite systems. Positional data can be visualised on the integrated high-resolution 1.14” LCD display. The board is further equipped with an accelerometer for motion sensing and five user-configurable buttons (Boot, Reset, Power, GP2, GP3) for direct control.

Expansion and data logging are facilitated by a microSD card slot, ideal for storing sensor data or application files. Connectivity is streamlined with a modern USB-C port for programming and power, alongside a 3.5mm audio jack. All necessary GPS and GSM antennas are onboard, ensuring a compact and ready-to-use form factor.

This comprehensive integration of processing power, dual wireless communication (cellular and local), positioning, display, and storage on a single board makes the IoTFi an exceptional platform for developing sophisticated IoT solutions, from asset trackers and remote monitors to smart agriculture and industrial automation prototypes.
