2.4GHz Wi-Fi 4 and Bluetooth 5.0 module with an ultra-compact formfactor - FCS940R - Quectel

April 27, 2024

FCS940R is a high-performance 2.4GHz Wi-Fi 4 and Bluetooth module in LCC package with an ultra-compact formfactor of 12.0mm × 12.0mm × 2.0mm. It enables seamless WLAN and Bluetooth connectivity and is designed to optimize end-product size and cost. It incorporates reliable SDIO 2.0 and HS-UART interfaces to provide robust WLAN capability.

FCS940R is a Bluetooth 4.2 compliant module that supports dual mode (BR/EDR + Bluetooth Low Energy). It enables scatternet topology and active links in both slave and master modes for BR/EDR. In Bluetooth Low Energy mode, it supports multiple functions, such as monitoring, broadcasting, scanning, and allows active links in master mode. Therefore, this module offers a comprehensive solution for high throughput performance in wireless LAN and Bluetooth applications.

Surface-mount technology (SMT) makes FCS940R an ideal solution for durable and rugged designs. The low profile and compact size of LCC package enable seamless integration into size-constrained applications, ensuring reliable connectivity. The advanced package design, combined with a laser-engraved label, improved heat dissipation and indelible markings allow for large-scale automated manufacturing, meeting stringent cost and efficiency requirements.
