Install the CH340 Drivers
Heads up! Previous versions of the SIK using the RedBoard Programmed with Arduino used the FTDI, which is a different USB-to-serial converter. Both function the same but require different drivers. If you look at the chip by the USB connector and you notice that it is the FTDI, make sure you follow the directions to install the drivers for the FTDI.
If you are using the RedBoard Qwiic, you will need to install drivers for the CH340.
The drivers for the CH340C might be pre-installed on Windows, Mac, and Linux. However, there are a wide range of operating systems and versions out there so we recommend installing the drivers to ensure that they work properly. Please go to How to Install CH340 Drivers for specific instructions on how to install the CH340C drivers with your RedBoard Qwiic.
