HUZZAH ESP8266

WiFi microcontroller HUZZAH ESP8266 Breakout

With this lovely, bite-sized WiFi microcontroller, you can add Internet to your next project, at a price you will definitely like.

This ESP8266 processor from Espressif is actually an 80 MHz microcontroller. It comes not only with a full WiFi front-end, either as client and access point, but also TCP/IP stack with DNS support. Although this chip has enjoyed great popularity, its use has also been quite difficult. Unlike Adafruit HUZZAH ESP8266 Breakout, most of the low cost modules do not come with an onboard 500mA 3.3V regulator or with level shifting. Most are not breadboard friendly and are not CE or FCC emitter certified.

The Adafruit HUZZAH ESP8266 breakout makes it very easy and fun to work with this chip. It is a certified module equipped with an onboard antenna and a lot of pins, soldered onto a breakout PCBs designed by Adafruit.

Onto this breakout it was also added:

• Reset button
• User button, it puts the chip into bootloading mode, too.
• Red LED you can blink
• Reset pin and level shifting on the UART
• 3.3V out, 500mA regulator (the ESP8266 can draw up to 250mA, then balancing in accordance)
• Two diode-protected power inputs (one for a battery and the other for the USB cable)

Thanks to two parallel, breadboard-friendly breakouts on either side, you have access to:

• 1 x Analog input (1.8V max)
• 9 x GPIO (3.3V logic), that also can be used for I2C or SPI
• 2 x UART pins
• 2 x 3-6V power inputs, enable, LDO-disable, reset and 3.3V output.

The breakout has an “FTDI” pinout at the end. This allows you to plug in a console cable or an FTDI and upload software and also, via the UART, read or write debugging information.

When you finish your coding, you can remove the cable and embed this tiny module into your project box.

Each module is pre-loaded with NodeMCU’s Lua interpreter (Note that NodeMCU 0.9.5 build 20150318 / Lua 5.1.4). Thanks to this you can run commands, and by using a USB-Serial converter cable, you can “save” Lua programs straight to the module’s Flash. If you want, you can skip Lua and simply use the Arduino IDE. Once downloaded, the ESP8266 core can be treated precisely as if it were a microcontroller+WiFi board. No need of other processors. On the below Technical details list, you find the link to NodeMCU’s Lua interpreter.

Every order is shipped with an already assembled and tested HUZZAH ESP8266 breakout board, with a stick of 0.1″ header You can solder it on and plug the breakout into a breadboard. Breadboard and cables shown in the photo are not included in this product. What you definitely need is a USB-serial cable to be able to upload software to the HUZZAH ESP8266. The essential tutorial by Adafruit shows downloads, wiring, pinouts, assembly, and other
