OEM installation mathod

Using ESP-12S module Please reference in front of the package information in the Layout on the main board for

OEM factory .Please pay more attention Module's direction and the antenna close to the edge of board is better ,the

Components and layout should not be on the bottom of antenna then soldering the module.when the module be

soldering can not in the environment of high temperature ,We recommend the reflow soldering temperature curves is
