The main differences are: 1.) 2-pin JST connector Looking at the ESP8266 Thing - Dev board, it was designed to keep the cost of the development board low and there were requests to keep the original ESP8266 Thing. This is quite a common question that we get. The converter does need a DTR line in addition to the RX and TX pins.

A 3.3V FTDI Basic is required to program the SparkFun ESP8266 Thing, but other serial converters with 3.3V I/O levels should work just fine as well. That means the ESP8266вЂ™s I/O pins also run at 3.3V, youвЂ™ll need to level shift any 5V signals running into the IC. The ESP8266вЂ™s maximum voltage is 3.6V, so the Thing has an onboard 3.3V regulator to deliver a safe, consistent voltage to the IC. LEDs towards the inside of the board indicate power, charge, and status of the IC. USB and LiPo connectors at the top of the board provide power вЂ“ controlled by the nearby ON/OFF switch. The pins are broken out to two parallel, breadboard-compatible rows. The SparkFun ESP8266 Thing is a relatively simple board.

You can even program the Thing through the Arduino IDE by installing the ESP8266 Arduino addon. The Thing does everything from turning on an LED to posting data with datastream, and can be programmed just like any microcontroller. Why the name? We lovingly call it the вЂњThingвЂќ due to it being the perfect foundation for your Internet of Things project. We've made the ESP8266 easy to use by breaking out all of the moduleвЂ™s pins, adding a LiPo charger, power supply, and all of the other supporting circuitry it requires. The Thing is low-cost and easy to use, and Arduino IDE integration can be achieved in just a few steps.

Note that for the first program, you have to change line #12 and #13 to the SSID and password of your wireless internet.The SparkFun ESP8266 Thing is a breakout and development board for the ESP8266 WiFi SoC вЂ“ a leading platform for Internet of Things (IoT) or WiFi-related projects. You should be good to go! Just run these two programs in serial and copy the IP address into your browser of choice. Make sure you reset everything before continuing just as a safe measure. Take DTR out of bootloader mode by removing it's connection to GND. If you are running into errors, fully unplug the MBED and re-power the ESP8266 Thing and try again. Navigate to the directory of esptool.py and run this command: I'm on OSX, and mine was located at /dev/tty.usbmodem1412.

Good information on how to do that is found in the esptool.py wiki here. MBEDДЄfter your MBED is plugged in, you can find it's port pretty easily. Make sure you connect both things into their power sources, and switch the ESP8266 Thing on. The rest of the connections are pretty self-explanatory. You can find more information in the jumpers section. Pull DTR low to ground so it will boot into bootloader mode (as per spec). Serial pass through program - version for mbed LPC1768

Updating sparkfun esp8266 firmware code#

This code allows for your computer to talk to the mbed and vice versa, you'll want to compile and put this on your mbed before running the esptool python script.

Updating sparkfun esp8266 firmware install#

An easier way to install is with pip: pip install pyserialДЇlashing Firmware Update (or Downgrade) MBED board as a serial passthrough.

Follow the installation instructions to get access to the esptool command in python.

This is used to flash the firmware onto the ESP8266.

In my example, I downloaded the v0.25.0.0 firmware.

You can download the latest firmware here.You'll want to visit a couple places before starting: If you have your hands on an FTDI cable, I'd recommend you use that. You can easily flash any ESP8266 chip with an FTDI cable, but you can easily save some beer money and flash it via the MBED. Special thanks go out to Austin mbed, Jim Hamblen, Sparkfun, and a bunch of random tutorials online. If you want to see them yourself, you'll find them below. Sources are put first because this tutorial will be very similar to them, with information pulled from everywhere to make one comprehensive guide.

You can use this tutorial to flash any firmware you desire. While there is a nice Arduino plugins, a NodeMCU firmware for running Lua scripts, and MicroPython support, this tutorial will demonstrate how to flash the ESP8266 with the AT command firmware through the MBED and allow the MBED to use the ESP8266 Thing as a server. This is an aggregation of information to be able to flash the newer ESP8266 Thing and use it in a similar fashion as the older ESP8266 breakout chip. However, the previous one was not fully broken out and thus hindered functionality. The ESP8266 is a pretty popular chip to add wifi communication to embedded projects.
