x5pcs Upgraded Version ESP8266 ESP-01 WIFI Serial Wireless Transceiver Module DESCRIPTION: 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. This module comes with AT commands firmware which allows you to get functionality like wifi shield, however you can load different firmwares to make your own applicaiton on the modules' memory and processor. This module has onboard 80Mhz low power 32 bit processor which can be used for custom firmwares. For more details see: NODEMCU (www.nodemcu.com/). 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. The ESP8266 Module is compatible only with 3.3V logic level and will not work directly with 5V devices (for both serial and GPIO access). You need a 3.3V compatible device or you will need to convert the levels before you use it. This module ESP01S has 2 GPIOs accessible on pin headers. -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 -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) -Access Point and Station Modes PACKAGE CONTAINS: - 5pcs ESP8266 Serial Esp-01 WIFI Wireless Transceiver Module
