These chips are responsible for managing the USB interface of the board. Since these chips manage the communication between our Arduino and the PC, we must have the appropriate driver installed for them to work without problems. Compatible Arduino boards work correctly on some system versions and with some versions of the IDE. However, there are some system-IDE combinations where the original Arduino IDE is not able to communicate with our compatible Arduino board. To solve the problem we must download the CH340 driver from the manufacturer's website (WCH).
