8. Electrostatic Protection
Although the ESD problem has been considered and ESD protection has been completed
in the FM101-NA-20 module design, the ESD problem may also occur in transportation
and secondary development. Developers should consider ESD protection in the final
product. In addition to ESD in packaging, customers should consider the recommended
circuit of the interface design in the document during module application.
The following table describes the ESD discharge range allowed by the FM101-NA-20
module.
