The low-power consumption micro-controller intentionally designed for Internet of Things (IoT) projects. The board integrates a Dual-Core ESP-WROOM-32 module, which supports MCU and Wi-Fi &Bluetooth dual-mode communication. DFR0478

Evaluation Kit with Bluetooth 5.0 BT401. It is equipped with a microSD slot, microUSB connector and two audio outputs. DFRobot DFR0782

2.4 GHz Bluetooth 4.0 communication module, based on the nRF51822 system. Designed for applications with low energy consumption.

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

BLE Beacon, which emits Bluetooth Low Energy signals, enabling discovery by Bluetooth devices such as smartphones or ESP32 without the need for pairing. With a built-in I2C interface and an 11-bit ADC, it allows data collection from various sensors, and its low power consumption (650nA in sleep mode) ensures long-lasting operation on a single battery, ideal for applications requiring mobility and long range. DFRobot TEL0168

Bluetooth module v2.0 + EDR (master / slave), controlled by AT + commands with built-in antenna.

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

Compact, low-power 2.4 GHz Bluetooth Beacon solution, ideal for sensor monitoring, asset tracking, and real-time location. With extremely low power consumption, it can operate for years on a 3V button cell battery, making it an efficient choice for IoT applications. Configuration of the module is simple and intuitive thanks to the InPlay NanoBeacon Config Tool, which enables easy programming without the need to write code, providing a user-friendly graphical interface to set the device parameters.
