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.
Features
- 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 <10mW (DTIM3)
Applications
- Smart power plugs
- Home automation
- Mesh network
- Industrial wireless control
