5.4.1 ESD Characteristics
MiniPCIe is a consumer product. Although the design of the module has considered the ESD issue and
provided ESD protection, the ESD issue may occur in the transport and secondary development, so
developers should consider ESD protection for the final product. In addition to considering anti-static
