IoTFi 2G / 4G DIY IoT Kit - Introduction

IoTFi is complete DIY kit designed for makers who wish to create or investigate a the possibilities of a 2G or 4G internet, GSM /GPS, Basic electronics, and much more. IoTFi has an onboard SIM868/7600G and RP2040, a powerful chip that comes from Raspberry Pi and ESP-C3 32S module is WiFi+ BLE combo with system-level processors (SoC) that are developed for various uses like Internet of things (IoT) mobile devices and smart home devices, wearable electronics and more. IoTFi is packed with advanced features. It can send as well as receiving text messages on any devices and calling GPS function, as well as IoTFi comes with an 3.5mm audio port as well as a micro-SIM slot to accommodate SIM868/7600G and the SD slot that has an type C connection.

The board is well-equipped and comes with high-resolution 1.14 inch LCD as well as an accelerometer and an accelerometer, as well as a Bluetooth 2.0 module that gives the board an easy-to-use experience when running applications.

This device is utilized for learning and teaching purposes that are unlimited, thanks to distinctive features and an easy-to-use performance.

 IoTFi is able to amplify itself with astonishing specifications. The package comes with an IoTFi device, GSM, and GPS antenna. To learn more, IoTFi can be programmed with a variety of programming languages like Arduino, Python, and C/C++.


It's accompanied by principal technical features, with there are many other things to note such as that of the SIM868 component. This comprehensive Quad-Band GSM/GPRS module makes use of GNSS (GPS/GLONASS/BDS) GPS/GLONASS/BDS satellite technology. It has a variety of interfaces, such as UART, USB2.0, GPIO and many more that also offer the flexibility.

 A small , quad-band GSM/GPRS+GNSS unit comes with an LCC+LGA form dimension with excellent interfaces. IoTFi devices operate on low power consumption thanks to embedded protocols for TCP/UDP and numerous software functions, including DTMF MMS, DTMF, and MUX. Multi-constellation GNSS receiver support like GPS, GLONASS, BeiDou.
