IoTFi cellular connectivity board with RP2040 microcontroller and inbuilt GPS technology
This one’s exciting! A UK-based embedded developer in collaboration with SB Components has designed an IoT development board with support for a rich set of connectivity options. The hardware platform has 2G and 4G cellular connectivity through a separate antenna for both. For 2G, the onboard SIM868 module supports GSM/GPRS and GNSS with low-power consumption and supported frequency bands of 800/900/1800/1900 MHz.
The IoTFi cellular connectivity board is built around the Raspberry Pi in-house silicon tapeout RP2040 microcontroller fabricated using 40nm silicon and comes with an integrated static RAM. The board also has an ESP32, a low-power system-on-chip with support for Wi-Fi and dual-mode Bluetooth wireless connectivity. The board is equipped with a 3.5mm audio jack and an SD card slot to expand the onboard storage.
Apart from the enhanced wireless experience, IoTFi cellular connectivity board features a high-resolution 1.14-inch LCD display for displaying various sensor parameters. There is also an onboard accelerator and Bluetooth 2.0 module, making the hardware platform run next-gen applications. As the company says, “This All-in-One device is capable of calling and transmitting messages to any of your devices.”
