# Wi-Fi & Bluetooth FC66E
## Key features
- Wi-Fi/Bluetooth module supporting 2.4 GHz, 5 GHz and 6 GHz triple-band and BLE (Bluetooth 5.3)
- Supports DBS
- Supports PCIe 3.0 interface, which provides higher data transmission rate and lower power consumption
- Fast time-to-market: simple design minimizes design-in time and development efforts
- Wide operating temperature range (-30°C to +75°C)
## Overview
FC66E is a high-performance Wi-Fi 6E and BLE (Bluetooth 5.3) module in LCC package. It can be used to establish WLAN and Bluetooth connections. Supporting 2×2 + 2×2 MIMO, it provides a maximum data rate up to 3000 Mbps.
With a compact and unified form factor of 19.9 mm × 18.0 mm × 2.1 mm, FC66E is an ideal Wi-Fi/Bluetooth solution for size-sensitive applications, and helps customers reduce product size and optimize application design cost. The surface-mount technology enhances its durability and robustness, and the LCC package ensures that the module can be easily embedded into size-constrained applications and provide reliable connectivity with these applications. The advanced package allows for large-scale automated manufacturing that has strict requirements on cost and efficiency.
Designed with a reliable PCIe 3.0 interface to provide WLAN capability, FC66E achieves low-power and high-speed data transmission. This, coupled with its compact size and extended temperature range, enables the module to meet Wi-Fi/Bluetooth application design requirements in industrial, consumer and automotive fields.
