Tips:
1.WIFI signal interferes with Bluetooth signal to some
extent, so bluetooth receiver cannot be too close to WIFI
signal source.
2. It is not necessary to insert and remove the shaft body
with great force. When you find that the shaft body needs
great force, it may be misaligned, please stop the operation,
otherwise the hot plug base will be damaged, or the solder
pad will fall off and the PCB will be directly discarded.
Matters needing attention:
