In addition, some wires and tools are used together as follows, such as:
(1) Two-end male USB cable (shown on the left in the figure below) and USB-Micro cable (shown on the right in the
figure below):
Note: This USB cable is a USB enhanced cable specially customized by our company, which can ensure that the
download can be successful when directly powered by USB. On the market, some relatively low-quality two-end male
USB cables have too much internal resistance and cause a large voltage drop (for example, the voltage of the USB
when it is empty is about 5.0V. When using a low-quality USB cable to connect U8W/U8W-Mini/U8 /U8-Mini, the
voltage to our download board may drop to 4.2V or lower, causing the chip to be in a reset state and fail to download
successfully).
(2) The download cable connecting U8W/U8W-Mini to the user system (ie the connecting cable between U8W/U8W-
Mini and the target MCU on the user board), such as
