This product is a DIP type module. When welding the module, the welding personnel must work in accordance with the
static discharge operation specifications;
This product is a static-sensitive product. The module may be permanently damaged if it is not welded according to the
rules.

12.Antenna Type

The antenna plays an important role in the communication process. The inferior antenna often has a great impact on the
communication system. Therefore, we recommend some antennas that support our wireless modules and have excellent
performance and reasonable price.
