The KT142X supports connecting to a computer via USB to download and update its firmware. The update software (exe) is provided by us.
Step 1: Connect to the computer via a USB cable—this essentially enters the firmware update process.
The update interface is the USB-A port on the test board,
that is, the larger USB port, the one used for connecting a U disk.
At this point, the most noticeable phenomenon is that the busy indicator light starts flashing rapidly.
You can also open the device properties in My Computer,
where an additional “USB Mass Storage Device” will appear.
Step 2: Open the update exe software we provide, click the “Update” button, then unplug the USB and power on again.
