IOTA-SYNC is a platform to teach the embedded system basics and Internet of things applications. This IOTA-SYNC 2 is second board in this series. This variant of the board uses AVR (Atmega328P), ESP8266 and SIM800L. Both MCUs operates at 3.3V voltage logic level same as that of sim800L to make the development more easier. Pin naming are mentioned in both AVR port naming scheme as well as that of Arduino platform naming scheme to save time while development.

Earlier variant of this board exposes ESP32 (WiFi, Bluetooth), NFC and LORA.
