WiFi Adafruit HUZZAH ESP8266 Breakout

WiFi Adafruit HUZZAH ESP8266 Breakout - Add Internet to your next project with an adorable, bite-sized WiFi microcontroller, at a price you like! 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. While this chip has been very popular, its also been very difficult to use. Most of the low cost modules are not breadboard friendly, don't have an onboard 500mA 3.3V regulator or level shifting, and aren't CE or FCC emitter certified....UNTIL NOW!

 

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. We added in:

  • 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)

Two parallel, breadboard-friendly breakouts on either side give you access to:

  • 1 x Analog input (1.8V max)
  • 9 x GPIO (3.3V logic), which can also be used for I2C or SPI
  • 2 x UART pins
  • 2 x 3-12V power inputs, reset, enable, LDO-disable, 3.3V output

One breakout at the end has an "FTDI" pinout so you can plug in an FTDI or console cable to upload software and read/write debugging information via the UART. When you're done with your coding, remove the cable, and this little module can be embeded into your project box.

Each module comes pre-loaded with NodeMCU's Lua interpreter (NodeMCU 0.9.5 build 20150318 / Lua 5.1.4 to be specific), you can run commands, and 'save' Lua programs directly to the module's Flash using a USB-Serial converter cable. But, if you'd like, you can skip Lua and go direct to using the Arduino IDE. Once you download the ESP8266 core, you can treat it just like a microcontroller+WiFi board, no other processors needed!

Each order comes with one assembled and tested HUZZAH ESP8266 breakout board, and a stick of 0.1" header that you can solder on and plug the breakout into a breadboard. A soldering iron and solder are required for that, and aren't included. Solderless breadboard also not included. You'll really want a USB-serial cable such as a USB console cable (good for Windows, not suggested for MacOSX users),  FTDI Friend (great for any OS), or FTDI cable (great for any OS)  to upload software to the HUZZAH ESP8266! Our essential tutorial has wiring, pinouts, assembly, downloads, and more!


TECHNICAL DETAILS

NodeMCU's Benefits over Arduino UNO

  • Better Memory & Processor: The NodeMCUhas a 4MB flash memory and an 80MHz clock speed.
  • TCP/IP Stack built-in - loT Ready: The NodeMCU has a WiFi connection and is capable of accessing the internet through WiFi. It functions best in loT applications.
  • Inexpensive: Much less expensive than the Arduino UNO is the ESP8266 chip-based NodeMCU microcontroller development board.
  • Breadboard-friendly and small: Testing various circuit designs with the NodeMCU can be done quickly and easily using a breadboard. The Arduino UNO, in comparison, cannot fit on a breadboard.

Arduino UNO has benefits over NodeMCU:

  1. Widespread support: Support is widely accessible for the Arduino UNO, and the global Arduino community is very active.
  2. Simpler communication with sensors and actuators: Contrary to NodeMCU, Arduino UNO handles 3.3V and 5V modules, simplifying interaction with a range of sensors and actuators. Up to 20V of electricity can be handled by the Arduino UNO. The NodeMCU, however, can only withstand voltages of up to 12V.
  3. Current per pin: the Arduino UNO's capacity for 40mA of current per pin.

Arduinovs Raspberry Pi

Let's examine each of these distinctions in more detail to comprehend Arduino vs. Raspberry Pi.

Working Principle of Arduino

Every Arduino is a certain kind of black programmable logic unit called a microcontroller, as was already described earlier. It makes no difference if the package is an older 28-pin DIP (dual-inline-pin) or a more contemporary SMD (surface-mounted device). Everything needed for computer operations is included on one tiny chip, including a microcontroller, a timer, memory, and the I/O ports the MCU uses to connect to an external digital medium.
The Arduino board's microcontroller is the primary element that carries out the device's primary functions; the remainder of the board, along with the Arduino software, serves as an interface.

Working Principle of Raspberry Pi 
The Raspberry Pi functions significantly different from the Arduino; in fact, it functions very similarly to a desktop computer. With an inbuilt ARM-compatible central processing unit (CPU) and on-board graphics processing unit, Raspberry Pi has a Broadcom CPU on a chip (SoC) (GPU).
Its central component, the Broadcom CPU, is coupled to the board's RAM, ports, and external storage. The Broadcom CPU is a creation of Broadcom Inc., a US-based American business with headquarters in San Jose, California, that creates, develops, manufactures, and exports a variety of semiconductor and infrastructure software products worldwide.
The HDMI, USB, and RJ45 connections are controlled by an operating system that is operated by the Broadcom CPU. The operating system also runs programs and displays a graphical user interface to the user.
Due to its architecture, Raspberry Pi is able to perform tasks that Arduino and its microcontroller are unable to. But not all applications require a fully functional computer of this kind.
