Test model: T102
T102 Wi-Fi module V1.0
1. Pr
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:
