ESP8266-1

The ESP-01 (ESP8266) is a compact self-contained Wi-Fi module with an integrated TCP/IP stack. Pre-programmed with AT command firmware, it can add Wi-Fi connectivity to any microcontroller with a UART interface. Can also run standalone as an application processor with GPIO peripherals. 1MB flash onboard.

Note: The ESP8266 operates at 3.3V logic only — it is NOT 5V tolerant. Use a logic level converter when interfacing with 5V dev boards.

Features:

1. Wi-Fi: 802.11 b/g/n, Wi-Fi Direct (P2P), Soft-AP
2. Integrated TCP/IP protocol stack
3. Pre-programmed AT command firmware
4. Onboard TR switch, balun, LNA, power amplifier
5. Integrated 32-bit CPU usable as application processor
6. Interfaces: SPI, UART, SDIO 1.1/2.0
7. Wake up and transmit in <2ms
8. Standby power: <1.0mW (DTIM3)
9. Flash: 1MB

Applications:

• Wi-Fi enablement for Arduino and microcontrollers
• IoT sensor nodes
• Standalone Wi-Fi devices and automation
