Hello. I will use 3 slave devices and masters in the project. in the project I will control the input output of some data with the HMI display. I have two options for master selection. one of them is Nextion NX8048K070_11C (ARM 108 MHz, https://www.itead.cc/wiki/NX8048K070) and the other is Arduino Due-CH340 (https://store.arduino.cc/usa/arduino-due). Which one is easier to choose. what is your suggestion as a communication protocol.
