Bluetooth module and other IoT module

Product Introduction

The CC3551E module is a WIFI+ Bluetooth dual-in-one wireless module designed based on CC3551E as the core. Wifi supports MAC, baseband and RF transceivers of IEEE 802.11b /g/n/ax at 2.4GHz and 5GHz, single-stream 20MHz channel, application throughput up to 20Mbps (UDP), hardware-based encryption and decryption, and supports WPA2 and WPA3. Supports 4-bit SDIO or SPI host interfaces. Bluetooth supports low-power Bluetooth® 5.4, LE encoding PHY (long range), LE 2M PHY (high speed), and broadcast extensions. The module is packaged with 18-pin stamp holes.
