ASIX Electronics Corporation Notice USB to LAN products 
Dear Customer:

If you got some problems on ASIX USB to LAN products, please download the How to identify authentic ASIX USB to LAN Products document to double check if your USB to LAN device includes an Non-authentic ASIX USB to LAN solution inside or not? If yes, please contact the manufacturer of your USB to LAN device to get proper drivers instead. ASIX DOES NOT GUARANTEE AND PROVIDE ANY SUPPORT FOR THOSE NON-AUTHENTIC ASIX PRODUCTS.

  Yes, I understand.

 AXM23001 -- IEEE 802.11b/g/n IoT WiFi Module Board

The AXM23001 802.11b/g/n Wi-Fi module, a new addition to ASIX’s original AXM22001 802.11b/g Wi-Fi module, is the expansion of its wireless modules product portfolio with for Internet of Things (IoT) applications. Leveraging prevalent Wi-Fi infrastructure in home and industrial environment, the AXM23001 provides cost effective wireless networking solution to enable simple, easy, and low cost Internet connection capability for a wide-range of home, industrial and consumer electronics, such as networked home appliances, security systems, BLE/ZigBee/Z-wave gateway, wireless analog/digital I/O, and serial to Wi-Fi device server.

The AXM23001 offers high performance ARM Cortex-M3 MCU with 2MB Flash memory, 2.5MB Data memory, SSL hardware accelerator, 802.11b/b/g compatible WLAN MAC/Baseband/RF, and a full suite of peripheral interfaces including UART, SPI, I²Cs, PWMs, GPIOs, and ADC . In addition to standalone application, AXM23001 with TCP/IP protocol suite running on-chip and various serial host interfaces supported, such as High Speed UART or High Speed SPI, can be used as a network coprocessor to offload TCP/IP and WLAN protocol processing loading from system CPU in an embedded system.

In order to simply and securely connect user’s devices to Wi-Fi using a smartphone/tablet app or a web browser, the AXM23001 supports multiple provisioning options including Simple Config API, WPS and AP mode. In addition, the AXM23001 supports Over the Air (OTA) firmware update over web server and Windows application utility via TFTP protocol.

With built-in Google Firebase API support for cloud connectivity, the ASIX’s IoT solution helps manufacturers to easily and rapidly connect Wi-Fi devices to the Internet for remote control and monitoring applications. The Firebase is a powerful platform for building iOS, Android, and web-based apps, offering real-time data storage and synchronization. All of user’s data is transferred over a secure SSL connection to provide the most secure way to build cloud application. Apps built with Firebase can be written entirely with client-side code and scale automatically.

The AXM23001 module has received certification from all major regulatory agencies in U.S., Canada, Europe, China, Japan, Korea, Taiwan, and Australia/New Zealand.
