- General Description
BDE-BW3551P1 module series is a 2.4GHz and 5GHz dual-band Wi-Fi 6 and Bluetooth 5.4 Low Energy wireless MCU module based on TI's SimpleLink™ Wi-Fi SoC (system-on-chip) CC3551E.
The module series offers the latest standards from Wi-Fi and Bluetooth Low Energy while maintaining compatibility with Wi-Fi 4 (802.11 a/b/g/n) and Wi-Fi 5 (802.11 ac).
The module series is an excellent choice to use in cost-sensitive embedded applications with RTOS software, bringing the efficiency of Wi-Fi 6 to embedded device applications for the Internet of Things (IoT), with a small PCB footprint and highly optimized bill of materials.
In order to meet different integration requirements, BDE offers different variants for this module series. They are listed in below table.
