## Overview
FCU743R is a high-performance Wi-Fi 4 and Bluetooth 5.2 module launched by Quectel, which supports 2.4 GHz and 5 GHz frequencies. Thus, it can be used for WLAN connection. With an ultra-compact size of 13.0 mm × 12.2 mm × 2.0 mm, the module optimizes the size and cost for end-products, which fully meets the demands of size-sensitive applications.

Designed with a reliable USB 2.0 interface, the module can ensure high sensitivity in interference environments, and the module can realize high-speed, low-power WLAN wireless transmission with a maximum data transmission rate of up to 150 Mbps.

Surface-mount technology (SMT) makes FCU743R an ideal solution for durable and rugged designs. The low profile and small size of LCC package ensure that it can be easily embedded into size-constrained applications and provide reliable connectivity with these applications. The advanced package and the laser-engraved label with better heat dissipation and indelible markings allow for large-scale automated manufacturing which has strict requirements on cost and efficiency.
