T102 Wi-Fi module V1.0
1. Product Overview
T102 is a low-power embedded Wi-Fi module developed by Shenzhen Shengchuangwei Technology
Co., Ltd. It consists of a highly integrated radio frequency chip RTL8710BN and a small number of
peripheral devices, built-in Wi-Fi network protocol stack and a wealth of library functions. The T102
embeds ARM-CM4 MCUs, 1Mbyte of flash memory, 256Kbytes of SRAM and a wealth of peripheral
resources.
The T102 runs the RTOS platform and integrates all Wi-Fi MAC and TCP/IP protocol libraries. Based
on these, users can develop embedded Wi-Fi products that meet their needs.
The functional schematic of the T102 is shown in Figure 1:

5 antenna information
5.1
Antenna type
Only the PCB onboard antenna is connected.
5.2
Reducing antenna interference
When using a PCB on-board antenna on a Wi‐Fi module, to ensure optimal Wi‐Fi performance, it is recommended
that the antenna portion of the module be at least 15 mm away from other metal parts.

Production Guide
The factory module storage conditions are as follows:
1. The moisture-proof bag must be stored in an environment with a temperature <30 ° C and a humidity
<85% RH.
2. For dry-packed products, the shelf life should be 6 months from the date of sealing of the package.
Precautions
1. In the whole process of production, the operator of each station must wear an electrostatic ring.
2. When operating, prevent the module from getting wet or dirty.
The host will Satisfy Class I or Class Ⅱ permissive change based this module FCC ID.
If the FCC identification number is not visible when the module is installed inside the host, then
the outside of the device into which the module is installed must also display a label referring to
the enclosed module. This exterior label can use wording such as the following: “Contains
Transmitter Module Contains FCC ID:2ASKS-T102 or “Contains FCC ID:2ASKS-T102 .Any similar
wording that expresses the same meaning may be used.
