Esp01 Esp 01 Esp8266 Wifi Module

Woh! Super low cost WiFi module is here, we are carrying it now! 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 (and that’s just out of the box)! The ESP8266 module is an extremely cost effective board with a huge, and ever growing, community. There are plenty discussion and happening in the official community: http://www.esp8266.com

Features:

• Power: 3.3VDC, proper 3.3V voltage regulator and level shifter is needed if you are interface with 5V system.
• 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
• Interfacee: SDIO 1.1 / 2.0, 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)

Picture above show the pinout of WiFi Serial Transceiver Module (ESP8266). The reason why we said not breadboard-friendly is because it will short-circuit the pin connection when you directly connect those pins to breadboard.
