This is the SparkFun ESP8266 Thing Dev Board – a development board that has been solely designed around the ESP8266, with an integrated FTDI USB-to-Serial chip. The ESP8266 is a cost-effective, and very capable WiFi-enabled microcontroller. Like any microcontroller, it can be programmed to blink LEDs, trigger relays, monitor sensors, or automate coffee makers, and with an integrated WiFi controller, the ESP8266 is a one-stop shop for almost any Internet-connected project. To top it all off, the ESP8266 is incredibly easy-to-use: firmware can be developed in Arduino, and uploaded over a simple, serial interface. The ESP8266 Thing Development Board breaks out all of the module’s pins, and the USB-to-serial converter means you don’t need any peripheral components to program the chip. Just plug in a USB cable, download the Arduino board definitions, and start IoT-ing.

Why the name? We lovingly call it the “Thing” due to it being the perfect foundation for your Internet of Things project. The Thing does everything from turning on an LED to posting data, and can be programmed just like any microcontroller. You can even program the Thing through the Arduino IDE by installing the ESP8266 Arduino addon.

The ESP8266 Thing Development Board is a relatively simple board. The pins are broken out to two parallel, breadboard-compatible rows. The USB connector sits next to an optional power supply input, and an ON/OFF switch – controlling power to the ESP8266 – sits next to that. And LEDs towards the inside of the board indicate power, charge, and status of the IC. The ESP8266’s maximum voltage is 3.6V, so the Thing has an onboard 3.3V regulator to deliver a safe, consistent voltage to the IC. That means the ESP8266’s I/O pins also run at 3.3V, you’ll need to level shift any 5V signals running into the IC. If your project requires a power source other than USB, the Thing Dev Board includes footprints for a 2-pin JST, 2-pin 3.5mm screw terminal, or a simple 0.1"-pitch 2-pin header. Unlike the original ESP8266 Thing, the ESP8266 Thing Dev Board does not have a built-in LiPo charger.

The Thing Dev Board even includes a PCB trace antenna as a default WiFi antenna, it’s cost-effective and actually works really well! If you need to connect a more sensitive antenna, or need to route outside an enclosure, a U.FL connector is also available on the board. Some soldering will be required to get the U.FL connector functioning but instructions can be found in the Hookup Guide we have written for the dev board.

Note: We’ve provided a few Example Sketches to experiment on your SparkFun ESP8266 Thing Development Board. These sketches can be found in the Hookup Guide in the Documents section below!

這是SparkFun ESP8266東西開發板 - 開發板已經圍繞ESP8266被單獨設計,帶有一個集成的USB FTDI到串行芯片。該ESP8266是一款性價比高,而且很能幹WiFi功能的微控制器。如同任何微控制器,它可以通過編程閃爍的LED,觸發繼電器,監視傳感器,或自動化咖啡機,並帶有集成的WiFi控制器,ESP8266是幾乎所有的互聯網連接的項目提供一站式服務。要最糟糕的是,在ESP8266是非常容易使用的:固件可以在Arduino的開發,並上載了一個簡單的串行接口。該ESP8266事情發展局打破了所有模塊的引腳,以及USB轉串口轉換器意味著你不需要任何外圍元件對芯片進行編程。只要插上USB數據線,下載Arduino板的定義,並啟動物聯網-ING。

為什麼叫?我們親切地稱之為“物”,因為它是為你的東西工程的互聯網完美的基礎。該做的事情一切從打開的LED與發布數據phant.io ,並且可以被編程就像任何微控制器。你甚至可以通過安裝程序通過Arduino的IDE的事情ESP8266 Arduino的插件

該ESP8266事情發展局是一個相對簡單的電路板。該引腳突破至兩個平行,線路板兼容行。 USB連接器坐在旁邊的一個可選的電源輸入,以及一個ON / OFF開關 - 控制電源ESP8266 - 坐在旁邊。並向董事會內部LED指示電,一充,和IC的狀態。該ESP8266的最大電壓為3.6V,這樣的事情有一個板載3.3V穩壓器,以提供安全,一致的電壓給IC。這意味著ESP8266的I / O引腳也可在3.3V運行,你需要進行電平轉換運行到IC的5V信號。如果你的項目需要USB以外的電源,東西開發板上有一個2針JST腳印,2針3.5毫米螺絲端子,或一個簡單的0.1“-pitch 2針接頭,與原來的ESP8266的事情,在ESP8266東西開發板不具有一個內置的鋰聚合物充電。

怪開發局甚至還包括一個PCB走線天線作為默認WiFi天線,它的成本效益和實際工作真的很好!如果您需要連接一個比較敏感的天線,或者需要路由的外殼之外,一個U.FL連接器也可在黑板上。一些焊接將需要得到U.FL連接器功能的說明,但可以在聯播指南中找到,我們已經寫了開發板。

注:我們提供了幾個例子草圖進行試驗的SparkFun ESP8266事情發展局。這些草圖可以接管指南在下面的文檔部分可以找到!
