11/20/2016: It is now possible to reflash the board to support MicroPython. 20/11/2016:
See these tutorials, you will need to reflash your ESP8266 module to support MicroPython.
Connect your next project to the Internet with this adorable, affordable and mini WiFi microcontroller! The ESP8266 processor from the Espressif company is an 80 MHz microcontroller incorporating full WiFi support (as well both in client mode and access point mode) and a TCP / IP stack with DNS support. Although the ESP8266 is really popular, this component is very difficult to use. Most inexpensive modules are not compatible with breadboards, don't have a voltage regulator (3.3V at 500mA), nor a logic level converter and are not CE certified or FCC transmitter. UNTIL NOW!
The HUZZAH ESP8266 Adafruit is a breakout designed to be super easy to use and with which you will have a lot of fun. Adafruit has selected the ESP8266 module certified and already equipped with an antenna. This version of the module has many pins, all available on the Huzza board.
This board includes:
- A Reset button.
- A user button also used to place the module in "Bootloading" mode,
- A red LED that you can flash,
- Logical level conversion (Level shifting) on the UART (serial port) and the Reset pin,
- A 3.3V regulator capable of delivering 500mA.
You should know that the ESP8266 consume up to 250mA (so you only have 250mA available for your project)
- Two protective diodes for power sources (one diode for the USB cable and the other diode for the battery input)
Two series of parallel connectors (breakouts) with an impaction compatible with breadboards. These connectors will give you access to:
- 1 x analog input (1.8V max)
- 9 x GPIOs (3.3V logic), which can also be used for I2C or SPI
- 2 x UART pins (serial port)
- 2 x power inputs (3 to 12V),
- Reinitialization (reset), enable, LDO-disable,
- 3.3V output
At one end of the board, there is a pinout "FTDI" allowing to connect a FTDI converter or a console cable so that you can upload / download your software on the HUZZAH. This FTDI connection also makes it possible to read / write debugging information via the serial port (UART). When you have finished programming the module, simply remove the cable (FTDI converter) and enclose your HUZZAH in a case.
Each module is preloaded with the Lua NodeMCU interpreter (NodeMCU 0.9.5 build 20150318 / Lua 5.1.4 to be more precise), Lua is incredibly powerful. Using the USB-Serial converter, you can execute commands and "save" your Lua script directly in the Flash memory of the module. But if you want, you can bypass Lua and use Arduino IDE directly. Once you have uploaded the Arduino support to your HUZZAH ESP8266, you can use it as a microcontroller + WiFi board, no need for an external processor!
For each order, you receive a HUZZAH ESP8266 board assembled and tested, as well as a row of connectors that you can weld on your board (to insert it on a breadboard). You will need a welding iron and a little weld to do this operation.
The breadboard, console cable, FTDI converter are not included with the Huzzah board.
You'll need a USB-serial cable like the console cable (good for Windows, not recommended for MacOSX users) or a USB-Serial converter USB-Serial converter (FTDI Friend, suitable for all OS), OR an FTDI cable (suitable for all the OS) in order to download your software to the HUZZAH ESP8266!
