Authorized North America Distributor Stamp

The ESP8285 is a compact, low-power, Wi-Fi SoC solution designed for the Internet of Things (IoT). This wireless chip follows the 802.11 b/g/n/e/I WLAN MAC protocol along with the latest Wi-Fi P2P and TCP/IP. The chip can also be applied to a micro-controller and a Wi-Fi adaptor through SPI/SDIP or I2C/UART interfaces.

With the Tensilica’s L106 Diamond series 32-bit microcontroller (MCU) the chip is often integrated with external sensors and other application-specific devices through the 17 GPIOs. It offers reliable performance as a standalone application or as the slave to a host MCU.

The Espressif Systems’ Connectivity Platform (ESCP) enables the following features:

  • Fast switch between sleep and wake-up mode
  • Adaptive radio biasing
  • Advanced signal processing
  • Spur cancellation
  • Radio co-existence mechanisms for common interference mitigation

Examples of major applications include:

  • Home automation
  • Smart lights and plugs
  • IP cameras
  • Baby monitors
  • Sensor networks
  • Security ID tags
  • Mesh networks
  • Industrial wireless control
  • Wearable electronics
  • WiFi location-aware devices
  • WiFi position system beacons

Features

  • 802.11 b/g/n/e/i support
  • Wi-Fi Direct (P2P) support
  • WPA/WPA2 PSK, and WPS driver
  • WMM power save U-APSD
  • Multiple queue management to fully utilize traffic prioritization
  • UMA compliant and certified
  • 802.1h/RFC1042 frame encapsulation
  • Seamless roaming support
