WizFi310 Shield

WizFi310 based Arduino compatible Wi-Fi shield
Product Overview
크기변환_3 WizFi310 sheild Version

WizFi310 offers a quick, easy, and cost-effective way for device and appliance manufacturers to add Wi-Fi capabilities to their products.

WizFi310 provides UART interfaces which enable connections to any embedded design utilizing an 8/16/32-bit microcontroller via simple AT commands.

WizFi310 is an ideal solution for organizations with limited or no Wi-Fi or RF expertise, as it does not only reduce RF design time but also removes the burden of testing and certification. This allows customers to focus on their core application and product development. WizFi310 is compliant with 802.11b/g/n.

This shield is pin compatible with Arduino UNO and also can be used in other Arduino pin compatible development platforms- e.g., WIZnet’s WIZWiki-W7500.  In addition, temperature, humidity, and CDS sensors are built in.
