[SC8905 EVM Review] + Unboxing test and driver installation [Copy link]

 

I received the express on Saturday and couldn't wait to open the box to check. In the anti-static packaging bag were a TTF to USB module and the protagonist of this test - the power control board. The following picture is the real thing:

Connect the TTF to USB module, plug it into the computer, and it will prompt you to install new hardware:

This TTF to USB module uses the common CH341 chip. There are many drivers for this chip, and my computer has already installed it. I don't know why it prompts me to install it again. I installed it, found the driver file, and ran the driver, but it didn't work:

So I tried to install it again, but it failed again. I opened the properties of the unknown device and upgraded the driver, but it didn't help. I tried again and again, and it didn't work all Sunday. I tried again on Monday, and finally deleted the "unknown device" manually. Then the system automatically added the device, and it worked this time:

After the interface is driven successfully, the next step is power-on test. Use an external power supply to provide 5V voltage access, connect the output end to a multimeter, and the output is displayed as 8.34V:

The next step will be to begin attempting to complete the required evaluation tasks.
