ESP8266 Thing – Dev Board (with Headers) 開發板 sparkfun原廠代理進口

 

這是SparkFun ESP8266 Thing開發板 – 一款專門圍繞ESP8266設計的開發板,集成了FTDI USB至串行芯片。 ESP8266是一款具有成本效益且功能強大的支持WiFi的微控制器。像任何微控制器一樣,它可以編程為閃爍LED,觸發繼電器,監測傳感器或自動化咖啡機。通過一個集成的WiFi控制器,ESP8266是幾乎所有與互聯網連接的項目的一站式商店。最重要的是,ESP8266非常易於使用;固件可以在Arduino中開發並通過簡單的串行接口上​​傳。 ESP8266 Thing開發板使用預先焊接的插頭打破了所有模塊的引腳,而USB到串行轉換器意味著您不需要任何外設組件來編程芯片。只需插入USB電纜,下載Arduino電路板定義,然後開始IoT-ing。

為什麼這個名字?由於它是物聯網(IoT)項目的完美基礎,我們將它稱為“事物”。 Thing通過phant.io完成從開啟LED到發布數據等任何事情,並且可以像任何微控制器一樣進行編程。您甚至可以通過安裝ESP8266 Arduino插件,通過Arduino IDE對Thing進行編程。

ESP8266事物開發板是一個相對簡單的電路板。引腳分成兩個並行的麵包板兼容行。 USB連接器位於一個可選電源輸入旁邊,一個ON / OFF開關 – 控制ESP8266的電源 – 位於旁邊。朝向電路板內部的LED指示IC的電源,充電和狀態。 ESP8266的最大電壓為3.6V,因此Thing擁有板載3.3V穩壓器,可為IC提供安全穩定的電壓。這意味著ESP8266的I / O引腳也運行在3.3V;你需要將流入IC的5V信號進行電平轉換。如果您的項目需要USB以外的電源,則Thing Dev Board包含2腳JST,2腳3.5mm螺絲端子或簡單的0.1英寸2腳接頭的腳印,與原始ESP8266 Thing不同, ESP8266 Thing Dev Board沒有內置的LiPo充電器。

Thing開發板甚至包括一個PCB跡線天線作為默認WiFi天線。它具有成本效益,效果非常好!如果您需要連接更靈敏的天線,或者需要在機箱外部佈線,則還可以在主板上使用U.FL連接器。為了使U.FL連接器正常工作,需要一些焊接,但是可以在我們為開發板編寫的“連接指南”中找到說明。

注意:我們已經提供了幾個示例草圖,供您在SparkFun ESP8266事物開發板上進行試驗。這些草圖可以在下面“文檔”部分的“連接指南”中找到!

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. 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 with pre-soldered headers, 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 (IoT) project. The Thing does everything from turning on an LED to posting data with phant.io, and can be programmed just like any microcontroller. You can even program the Thing through the Arduino IDE by installing the ESP8266 Arduino add-on.

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 toward 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 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 with on your SparkFun ESP8266 Thing Development Board. These sketches can be found in the Hookup Guide in the Documents section below!
