Product Details
  • All module pins broken out for ease of use. On-board FTDI USB-to-Serial. +19.5dBm output power in 802.11b mode
  • 802.11 b/g/n. Wi-Fi Direct (P2P), soft-AP. Integrated TCP/IP protocol stack
  • Integrated TR switch, balun, LNA, power amplifier and matching network. Integrated PLLs, regulators, DCXO and power management units
  • Integrated low power 32-bit CPU could be used as application processor
  • The USB-to-serial converter means you don't need any peripheral components to program the chip. Simply plug in a micro USB cable.

  • Manufacturer: SparkFun Electronics
  • Model Number: WRL-13711
  • Part Number: WRL-13711

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. It can be programmed to blink LEDs, trigger relays, monitor sensors, or automate coffee makers, and 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 multiple IDEs, and uploaded over a simple, serial interface. The board breaks out all of the module’s pins, 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 compatible with Arduino board definitions, and start IoT-ing.

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 towards 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 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 Board includes footprints for a 2-pin JST, 2-pin 3.5mm screw terminal, or a simple 0.1"-pitch 2-pin header. This board has 4Mbit SPI (512KB) on board flash memory.

The Thing Dev Board even includes a PCB trace antenna as a default WiFi antenna, it’s cost-effective and actually 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.
