
It is assumed that there are devices with large electromagnetic interference around the module that will greatly
affect the performance. It is recommended to keep them away from the module according to the strength of the
interference. If necessary, appropriate isolation and shielding can be done;

Assume that there are traces with large electromagnetic interference (high-frequency digital, high-frequency analog,
power traces) around the module that will greatly affect the performance of the module. It is recommended to stay
away from the module according to the strength of the interference.If necessary, appropriate isolation and shielding
can be done;

If the communication line uses a 5V level, a 1k-5.1k resistor must be connected in series (not recommended, there is
still a risk of damage);

Try to stay away from some physical layers such as TTL protocol at 2.4GHz , for example: USB3.0;

The mounting structure of antenna has a great influence on the performance of the module. It is necessary to ensure
that the antenna is exposed, preferably vertically upward. When the module is mounted inside the case, use a good
antenna extension cable to extend the antenna to the outside;

The antenna must not be installed inside the metal case, which will cause the transmission distance to be greatly
weakened.

The TDO / TDI pin of the simulator is connected to the SWDIO pin of the module;
The TCK pin of the simulator is connected to the SWCLK pin of the module;
When the module itself is powered, VCC_TARGET is connected to the 3.3V pin of the
