Product Information

Back to top
Type1HD Wi-Fi module is a small, low power, self contained, certified embedded Wi-Fi network controller solution for cunsumer grade applications. It is enabled with Cypress Wireless Internet Connectivity for Embedded Devices (WICED) architecture. They host the Wi-Fi, TCP/IP network stack, security supplicant, and other network application features.

To develop software by Cypress Standard SDK (WICED SDK), please go to Cypress WICED website - WICED™ SDK

WICED™ is a Cypress development system that vastly reduces the effort required to add wireless connectivity to embedded devices. The SDK enables developers to quickly create network connected applications targeted for low-resource microcontrollers.

The WICED™ SDK includes:

  • An open source build system and toolchain based on GNU make.
  • A GUIDE based on Eclipse CDT that seamlessly integrates with a programmer and single-step, thread-aware, debugger based on OpenOCD and gdb.
  • A complete software stack that includes advanced security and networking features such as SSL/TLS, IPv4/IPv6 networking, and mDNS/Bonjour.
  • Production ready example applications.
