IoTFi 4G All-in-one RP2040 IoT Board with WiFi, 4G LTE & LCD Display

The IoTFi is a powerful all-in-one IoT development board designed for robust, connected projects. Based on the versatile RP2040 microcontroller and integrating an ESP32 module, it provides dual-core processing, WiFi, and Bluetooth connectivity right out of the box. Its standout feature is the onboard SIM7600G multi-band 4G LTE module, offering global cellular connectivity via a micro SIM card slot for applications where WiFi is unavailable or unreliable.

This compact board is packed with features to accelerate prototyping and deployment. A high-resolution 1.14-inch LCD display (135x240 pixels) provides a local interface for data visualisation and status updates. For data logging and storage, a microSD card slot is included. The board also features an accelerometer, five user-programmable buttons (Boot, Reset, Power, GP2, GP3), and both USB-C and 3.5mm audio connections for power, programming, and audio output.

Key Cellular & Connectivity Features

The integrated SIM7600G module supports LTE CAT1, enabling downlink speeds up to 10 Mbps and uplink speeds up to 5 Mbps. It is compatible with LTE-FDD, LTE-TDD, HSPA+, GSM, GPRS, and EDGE networks, ensuring broad global coverage. Onboard GPS and GSM antennas are included, eliminating the need for external antenna connections in many scenarios. The module uses an LCC+LGA form factor and comes with embedded TCP/UDP protocols, simplifying internet communication in your code.

Ideal for a Wide Range of Applications

This all-in-one solution is perfect for developers creating remote monitoring systems, GPS trackers, telemetry data loggers, smart agriculture sensors, or any IoT device requiring reliable internet access beyond local WiFi range. Its combination of processing power, multiple connectivity options, and onboard interfaces makes it an exceptionally versatile tool for bringing sophisticated IoT concepts to life efficiently.
