ESP8266(01) WIFI module

The ESP8266 WiFi Module is a self contained SOC with integrated TCP/IP protocol stack that can give any
microcontroller access to your WiFi network. The ESP8266 is capable of either hosting an application
or offloading all Wi-Fi networking functions from another application processor. Each ESP8266 module
comes pre-programmed with an AT command set firmware, meaning, you can simply hook this up to your
Arduino device and get about as much WiFi-ability as a WiFi Shield offers.
This module has a powerful enough on-board processing and storage capability that allows it to be
integrated with the sensors and other application specific devices through its GPIOs with minimal
development up-front and minimal loading during runtime. Its high degree of on-chip integration
allows for minimal external circuitry, including the front-end module, is designed to occupy minimal
PCB area. The ESP8266 supports APSD for VoIP applications and Bluetooth co-existance interfaces, it
contains a self-calibrated RF allowing it to work under all operating conditions, and requires no external RF parts.

Note: The ESP8266 Module is not capable of 5-3V logic shifting and will require an external Logic
Level Converter. Please do not power it directly from your 5V dev board.

Note: This new version of the ESP8266 WiFi Module has increased the flash disk size from 512k to 1MB.

Features:

802.11 b/g/n
Wi-Fi Direct (P2P), soft-AP
Integrated TCP/IP protocol stack
Integrated TR switch, balun, LNA, power amplifier and matching network
Integrated PLLs, regulators, DCXO and power management units
+19.5dBm output power in 802.11b mode
Power down leakage current of <10uA 1MB Flash Memory Integrated low power 32-bit CPU could be used as application processor SDIO 1.1 / 2.0, SPI, UART STBC, 1×1 MIMO, 2×1 MIMO A-MPDU & A-MSDU aggregation & 0.4ms guard interval Wake up and transmit packets in < 2ms Standby power consumption of < 1.0mW (DTIM3)
