Silex Unwired

Embedded Wi-Fi plus Bluetooth USB Combo Module for your Connected Devices

The use of USB in embedded systems is relatively new and not as popular as other interfaces, such as SPI, UART, SDIO, and PCIe for embedded solutions. USB Wi-Fi radios typically targeted non-embedded consumer applications because migrating to USB was difficult due to higher costs combined with a short life cycle. However, with the introduction of new MCUs with native USB interfaces, Wi-Fi modules with USB interfaces can now be a better solution for your embedded application. USB Wi-Fi radios are typically external dongles for consumer devices like PC's and TV's, but using Silex's latest USB wireless module, you can embed Wi-Fi and Bluetooth if your MCU has an available USB interface.


Silex has introduced SX-USBAC, our IEEE 802.11a/b/g/n/ac Wi-Fi plus Bluetooth USB Combo module, a dual-band IEEE 802.11 ac WLAN USB module plus Bluetooth 5.0 BR/EDR/LE combo module. Based on Qualcomm's QCA9377-7 System-on-Chip, it supports 1x1 MU-MIMO technology and delivers a reliable wireless PHY data rate up to 433Mbp. It's the ideal choice for USB wireless embedded systems that demand robust link quality and maximum throughput range.

SX-USBAC comes in multiple form factors to fit various platforms and size requirements.
