General Description

BDE-BW3351xP1 is a 2.4-GHz & 5-GHz dual-band Wi-Fi 6 and Bluetooth Low Energy 5.4 combo wireless module series based on TI’s CC3351. This module series is ideal for cost-sensitive embedded applications with a Linux or RTOS host running TCP/IP, where the peak application throughput requirement is a maximum of 50 Mbps and also has requirement for BLE connectivity. The BDE-BW3351xP1 module series is an excellent choice for bringing the efficiency of Wi-Fi 6 to embedded device applications, featuring a small PCB footprint and a highly optimized bill of materials for lower costs. Additionally, the module is backward compatible with Wi-Fi 4 (802.11 b/g/n) and Wi-Fi 5 (802.11 ac).

In order to fulfil different integration requirements, BDE offers various variants. They are listed in Table 1.
