There are a variety of designs based around the ESP8266, including tiny, modular boards and more accessible development boards like our very own SparkFun ESP8266 Thing. The ESP8266 WiFi Shield finds a middle ground between the Module and the Thing that provides a great introduction to the ESP8266 – without leaving the comfortable hardware confines of your Arduino. If you just have an Arduino project that needs an inexpensive gateway to the Internet, the ESP8266 WiFi Shield does everything from turning on an LED to posting data with phant.io. ## Pricing - **Price:** $33.05 (inc GST) — $30.05 AUD, exc GST - **Quantity discounts:** 5+ $29.15 (exc GST) · 25+ $28.55 (exc GST) · 100+ $27.35 (exc GST) ## Availability & dispatch - Available with a lead time — expect dispatch between Aug 20 and Aug 26. ## How to buy - **Build a cart:** compose `https://core-electronics.com.au/cart/link?items=WRL-13287:1` (comma-separated SKU:qty pairs) and share the link. Opening it shows a confirmation page with live pricing and stock before anything is added to the cart. - **Verify the cart first:** fetch `https://core-electronics.com.au/cart/link/WRL-13287:1.md` for live line prices (inc & exc GST, quantity discounts applied), stock and dispatch estimates, and totals. Append `/to/{AU-postcode}` (or `/to/{country-code}:{postcode}`) before `.md` for delivery options and prices to that destination. Unknown, retired, or out-of-stock SKUs are flagged. (Query form `cart/link.md?items=...` also works but some robots parsers refuse query strings here.) - **Checkout** is completed on-site and includes a captcha at the payment step. Share the cart link; checkout takes it from there. - **Search the catalogue:** `https://core-electronics.com.au/search/{query}.md` (URL-encode the query; pages 2-3 at `search/{query}/{page}.md`; `search.md?q=` also works) - **Payment methods, purchase orders, policies and contact details:** https://core-electronics.com.au/llms.txt ## Description The SparkFun ESP8266 WiFi Shield is an Arduino compatible shield for the ESP8266 WiFi SoC – a leading platform for Internet of Things (IoT) or WiFi-related projects. There are a variety of designs based around the ESP8266, including tiny, modular boards and more accessible development boards like our very own SparkFun ESP8266 Thing. The ESP8266 WiFi Shield finds a middle ground between the Module and the Thing that provides a great introduction to the ESP8266 – without leaving the comfortable hardware confines of your Arduino. If you just have an Arduino project that needs an inexpensive gateway to the Internet, the ESP8266 WiFi Shield does everything from turning on an LED to posting data with phant.io. The ESP8266 WiFi Shield comes pre-flashed with an AT-command firmware, so it can be controlled by any UART, but it also breaks out and provides command access to all of the ESP8266’s I/O. Since this is an Arduino shield, it makes it easy to attach to any development board that utilizes the Arduino R3 layout. All it will take is a little soldering to attach the necessary headers. The ESP8266 is much more than a simple serial-to-WiFi gateway. It has almost a dozen I/O that can be configured as digital inputs or outputs – it even has an ADC! These GPIO are all broken out towards the top-left side of the shield. Additionally, the ESP8266 WiFi Shield can be repurposed and reprogrammed through the programming port found on the top-right side of the shield. Whether you want to add AT commands of your own, or flash custom firmware on the ESP8266, this port may come in very handy especially with it utilizing the pinout of our FTDI Basic breakouts. This shield comes populated with all components as shown in the images and schematic; but it does not come with headers installed. Sparkfun recommend the [Arduino R3 Stackable Header Kit](https://core-electronics.com.au/search/?q=11417).
