Air-Conditioner Controller System

- Fully compatible with Arduino Uno R3.

- Optical isolation of USB conversion port to UART TTL, power supply for USB communication block completely isolated from MCU source, so the circuit board works very stable, suitable for measurement and data collection applications (DAQ) without worrying about disconnection.

- Circuit board using USB 2.0 conversion chip to UART TTL FT232 of FTDI company for fast loading speed and stable communication, this is the most advanced chip currently in the world in USB conversion to UART.
