ESP8266 low-cost Wi-Fi full stack TCP/IP MCU (Arduino Compatible)

ESP8266 is a tiny extremity cheap MCU with third-party library making it Arduino compatible. Features all the normal connections you would expect such as GPIO, SPI, I2C, I2C and UART to name a few, the biggest selling point is its size and build in WiFi support with full stack TCP / IP communications.

Great for those IoT projects, connected devices and internet / network projects.

Features

  • 32-bit RISC CPU: Tensilica Xtensa L106 running at 80 MHz*
  • 64 KiB of instruction RAM, 96 KiB of data RAM
  • External QSPI flash: 512 KiB to 4 MiB* (up to 16 MiB is supported)
  • IEEE 802.11 b/g/n Wi-Fi
    • Integrated TR switch, balun, LNA, power amplifier and matching network
    • WEP or WPA/WPA2 authentication, or open networks
  • 16 GPIO pins
  • SPI
  • I²C
  • I²S interfaces with DMA (sharing pins with GPIO)
  • UART on dedicated pins, plus a transmit-only UART can be enabled on GPIO2
  • 10-bit ADC (this is a Successive Approximation ADC)
