Bluetooth/WiFi Combo - BDE-BW3551 (TI CC3551 Dual-band Wi-Fi 6 & BLE, -40°C to 85°C）
  • BDE-BW3551 (TI CC3551 Dual-band Wi-Fi 6 & BLE, -40°C to 85°C）
  • General Description

    BDE-BW3551 is a 2.4-GHz & 5-GHz dual-band Wi-Fi 6 and BLE Combo wireless MCU module series based on TI’s SimpleLink™ Wi-Fi System-on-Chip CC3551. This module series is ideal for cost-sensitive embedded applications with RTOS software, where the peak application throughput requirement is a maximum of 20 Mbps. The BDE-BW3551 module series is an excellent choice for bringing the efficiency of Wi-Fi 6 to embedded device applications for the Internet of Things (IoT), 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).
