ماژول وای فای ESP8266-12S

برخی از معایب ماژول وای فای ESP8266-12S عبارتند از:

• حساسیت به نویزهای الکترومغناطیسی

•  عمر مفید کوتاه‌تر نسبت به ماژول‌های دیگر

•  حافظه دستگاه کمتر از حافظه ماژول‌های دیگر است

•  امکان اتصال به شبکه‌های بزرگتر از ۳۲ کاراکتر ندارد

•  محدودیت در سرعت انتقال داده‌ها به علت محدودیت فرکانس ساعت

•  ارتباط برقرار شده با ترمینال‌های دیگر قابل ردیابی است.

Introduction

This ESP-12S WiFi module has core processor ESP8266 in smaller sizes of the module encapsulates Tensilica L106 integrates industry-leading ultra low power 32-bit MCU micro, with the 16-bit short mode, clock speed support 80 MHz, 160 MHz, supports the RTOS, integrated Wi-Fi MAC/BB/RF/PA/LNA, on-board antennas. The module supports standard IEEE802.11 b/g/n agreement, complete TCP/IP protocol stack. Users can use the add modules to an existing device networking, or building a separate network controller. ESP8266 is high integration wireless SOCs, designed for space and power constrained mobile platform designers. It provides unsurpassed ability to embed Wi-Fi capabilities within other systems, or to function as a standalone application, with the lowest cost, and minimal space requirement.
