Overview

The Adafruit HUZZAH ESP8266 breakout is what we designed to make working with this chip super easy and a lot of fun. We took a certified module with an onboard antenna, and plenty of pins, and soldered it onto our designed breakout PCBs.

The ESP8266 processor from Espressif is an 80 MHz microcontroller with a full WiFi front-end (both as client and access point) and TCP/IP stack with DNS support as well. 

Technical Details of HUZZAH Breakout

  • Reset button,
  • User button that can also put the chip into bootloading mode,
  • Red LED you can blink,
  • Level shifting on the UART and reset pin,
  • 3.3V out, 500mA regulator (you'll want to assume the ESP8266 can draw up to 250mA so budget accordingly)
  • Two diode-protected power inputs (one for a USB cable, another for a battery)
  • Dimensions: 25mm x 38mm x 5mm / 1" x 1.5" x 0.2"
  • Weight: 5g
  • 1 x Analog input (1.0V max)
  • 9 x GPIO (3.3V logic), which can also be used for I2C or SPI
  • 2 x UART pins
  • 2 x 3-6V power inputs, reset, enable, LDO-disable, 3.3V output

Technical Details of ESP8266

  • 802.11 b/g/n protocol
  • Wi-Fi Direct (P2P), soft-AP
  • Integrated TCP/IP protocol stack
  • Integrated TR switch, balun, LNA, power amplifier and matching network
  • Integrated PLL, regulators, and power management units
  • +19.5dBm output power in 802.11b mode
  • Integrated temperature sensor
  • Supports antenna diversity
  • Power down leakage current of < 10uA
  • Integrated low power 32-bit CPU could be used as application processor
  • SDIO 2.0, SPI, UART
  • STBC, 1×1 MIMO, 2×1 MIMO
  • A-MPDU & A-MSDU aggregation & 0.4μs guard interval
  • Wake up and transmit packets in < 2ms
  • Standby power consumption of < 1.0mW (DTIM3)
