A simple USB wireless network card, the WIFI module uses the must-connect BL-R8188EU1; the LDO linear regulator uses SPX3819, and the power chip can choose a fixed 3.3V output or an adjustable output. Because this WIFI module only supports the 2.4G frequency band, the antenna can be a 2.4G glue stick folding antenna.
After welding, check that the LDO input and output voltages are normal, and then you can plug it into the computer for use. If the driver is not installed, you can use third-party software such as Driver Wizard and Driver Master to install the driver.
