Adafruit 2479 - Bluefruit LE UART Friend - Bluetooth Low Energy (BLE)

Adafruit 2269 - Bluefruit LE Sniffer - Bluetooth Low Energy (BLE 4.0) - nRF51822 - v1.0

The BLE Nano from RedBearLab is the smallest Bluetooth 4.1 Low Energy (BLE) development board on the market. With the included MK20 USB in this kit, you’ll be able to deploy firmware to BLE Nano even easier. WRL-14071/WRL-13730

HC-08 is a module operating in the Bluetooth Low Energy 4.0 standard. The system has a built-in antenna and small dimensions, and thanks to edge joints it can be surface soldered. The module is configured via AT commands

Expansion board with BlueNRG-M0 module compatible with Bluetooth v4.2. It is compatible with the ST morpho connector system (unmounted) and Arduino UNO R3. Communication with the module is via the SPI interface. STMicroelectronics X-NUCLEO-IDB05A2

Mini bluetooth v2.0, plug & play USB module, RoHS

Bluetooth 4.0 BLE module with UART serial interface. Controlled by AT commands, it can be supplied with the voltage from 3.6 V to 6 V. AT-09/HM-10

Advanced wireless communication module, based on the Bluetooth 5.4 stack (Bluetooth® Low Energy, BLE), which was designed using the efficient Nordic NRF52805 SOC system. The module offers support for the UART interface, available only in peripheral mode, which allows for effective operation as a data bridge (Data Bridge). Sparkfun WRL-25466

BLE4.0 Bluetooth 2.4G Wireless Module, nRF51822 Onboard. Core51822

Powerful, generic Wi-Fi+BT+BLE MCU modules that target a wide variety of applications, ranging from low-power sensor networks to the most demanding tasks, such as voice encoding, music streaming and MP3 decoding. Espressif ESP32-WROOM-32E 32MBit (4MB)

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

A module that combines GSM/GPRS/GNSS and BT 3.0 technologies. It is available in a small, easy to solder LCC housing and has a low power consumption up to 1.2 mA. Quectel MC60CA

The IoT module combining Wi-Fi and Bluetooth (BLE) technologies, which is designed for a wide range of applications, from low-power sensor networks to the most demanding tasks such as voice coding, music streaming and MP3 decoding. Espressif ESP32-WROOM-32D 128MBit
