The ESP-WROOM-02 module is a highly integrated WiFi 802.11 b/g/n module that consumes extremely low power while providing a wireless internet connection for embedded devices. With a very small form factor, this wireless module easily assimilates into resource limited devices. These features make it a great choice for OEMs to connect their IoT (Internet of Things) applications. ESP-WROOM-02 is a 32-bit low power micro-controller (MCU) that integrates with TCP/IP network stacks; the included 10-bit ACD interfaces with HSPI, SDIO, UART, PWM, I2C and I2S. Programs and firmware can be stored in the integrated SPI flash with 32MB capacity.This WiFi module has a wake up and transmit packet speed of less than 2ms which makes it a great solution for applications including IoT. Examples are:

  • Home automation and home security
  • Smart lights and plugs
  • Home appliances
  • Sensors and detectors
  • Security alarms
  • Monitor and scales
  • Mesh Networks
  • Industrial Wireless Control
  • Wearable Electronics
  • WiFi Location-aware Devices
  • WiFi Position System Beacons
