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/ADA3654:1.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 Connect your Arduino-compatible to the Internet with this WiFi shield that features the FCC-certified ATWINC1500 module from Atmel. This 802.11bgn-capable WiFi module is the best new thing for networking your devices, with SSL support and rock solid performance - running Adafruit's adafruit.io MQTT demo for a full weekend straight with no hiccups (it would have run longer but Adafruit had to go to work, so they unplugged it). The **Adafruit ATWINC1500 WiFi Shield** uses SPI to communicate plus some GPIO for control, so with about 6 wires, you can get your wired up and ready to go. Right now the Atmel-supplied library works best with SAMD21-based boards like the Arduino Zero or [Metro M0 Express](https://core-electronics.com.au/adafruit-metro-m0-express-designed-for-circuitpython-atsamd21g18.html), or the Arduino Mega. It works OK on Uno but uses nearly all the memory so it may be a challenge to build complex projects. It will not work/fit on other Arduinos such as 32u4-based or attiny-based boards. You can clock it as fast as 12MHz for speedy, reliable packet streaming. And scanning/connecting to networks is very fast, a few seconds. This module works with 802.11b, g, or n networks & supports WEP, WPA and WPA2 encryption. You can use it in Soft AP mode to create an ad-hoc network. For secure client connections, there is TLS 1.2 support! This version of the shield comes with a uFL connector that can be used to attach external antennas. If you want to keep it simple, [check Adafruit's the PCB trace antenna version here.](https://core-electronics.com.au/adafruit-winc1500-wifi-shield-with-pcb-antenna.html) These SPI-protocol WiFi module are currently the best way to add WiFi to your Arduino-compatible so they have decided to make a handy shield for it. The shield comes with level shifting on all the input pins so you can use it with 3V or 5V logic boards. A 3.3V voltage regulator that can handle the 300mA spikes lets you power from 3-5.5VDC. There's also 3 LEDs that you can control over the SPI interface (part of the library code) or you can have controlled by the Arduino library. They'll light up when connected to an SSID, or transmitting data. They also tossed on a micro SD card socket, you can use that to host or store data you get from the Internet. Arduino's based on the ATmega328 (like the UNO) cannot use both the WiFi module and SD library at the same time, they're too small. Upgrade to a [Metro M0 Express](https://core-electronics.com.au/adafruit-metro-m0-express-designed-for-circuitpython-atsamd21g18.html) to get a big memory bump! ## Technical Details Product Dimensions: 68.0mm x 53.0mm x 4.7mm / 2.7" x 2.1" x 0.2" Product Weight: 13.6g / 0.5oz ## Images - [Product image 1](https://core-electronics.com.au/media/catalog/product/3/6/3654-00.jpg)
