I²C Remote Interface smartNode​

The smartNode smart device shares the same functions with the smartWiFi and the smartBLE.

Contrary to the smart devices relying on Blynk, smartNode allows to display multiple text outputs. As a consequence, ​sW_setText replaces sW_printText, with two inputs: variable number and text.

The device connects to the I²C port of the RoboTX and is powered by the RoboTX.
• Caution
