Adafruit HUZZAH ESP8266 Breakout Board 这是一个Adafruit推出的基于ESP8266的WIFI开发板。可以像Arduino一样操作硬件IO提供硬件的高级接口。Adafruit HUZZAH ESP8266 Breakout Board is an 80MHz microcontroller with a full Wi-Fi front-end (both as client and access point) and TCP/IP stack with DNS support. The ESP8266 is breadboard friendly, has an onboard 500mA 3.3V regulator, level shifting and is CE or FCC emitter certified. It's designed to be super easy and a lot of fun. The ESP8266 is a certified module with an onboard antenna and plenty of pins, soldered onto designed breakout PCBs.Added Features:
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)
Onboard 500mA 3.3V regulator, level shifting, and CE/FCC emitter certified.?
