The HLK-B35S module is a compact Wi-Fi + BLE solution for wireless communication in IoT and automation projects. modHLK-B35S

The module with the HC-05 transceiver makes it easy to add Bluetooth communication to an existing project. The system is controlled by exchanging AT commands (UART bus). FC-114

PmodBT2 - Bluetooth Interface

Wireless connectivity module based on the CYW43439, providing Wi-Fi and Bluetooth for projects with RP2040 or RP2350 microcontrollers. Equipped with an SP/CE (JST-SH 8-pin) connector, it allows for quick, solderless connection, and optional pads allow for permanent wired connections. It is fully compatible with Pico W and ideal for IoT, automation, and mobile applications. Pimoroni PIM730

WiFi/BLE module that supports both the 2.4 GHz and 5 GHz WiFi bands, as well as Bluetooth Low Energy (BLE 4.2) communication. It has a built-in chip antenna and 2.54 mm pitch connectors, which greatly facilitate prototyping. Tibbo WA2000C

BLE Beacon transmitting Bluetooth signals at regular intervals. These signals can be detected by Bluetooth-enabled devices such as the SenseCAP T1000 tracker, allowing them to determine their distance from the beacon, creating a location-based indoor positioning solution. Seeed Studio 113991194
