A major part of any new IoT project involves integration and interfacing now a days. In IoT world we have a lot of proprietary technologies and thus a good number of protocols and interfacing techniques like UART, SPI, I2C, PCIe, SWP, DWP, which makes the life of a new IoT Engineer really challenging. In 3 in 1IoT Bundle, we consider all those scenario in details and step by step manner.3 in 1 IoT Bundles cover integration of each popular hardware with its SDK hands-on. Most of these IoT development platform has its own pros and cons which is covered in details with use cases3 in 1 IoT have covered majorly hardware side of IoT, as this is the first and major point where software developers face challenges. We have covered 4 major hardware development and integration, which is Arduino Uno, Raspberry Pi, Konnect KiT and wireless enabled ESP8266.
