€8.00
Tax included

BC-04 Bluetooth serial module (HC-05 compatible), operating at 3.3V with the CSR BlueCore4 chipset. Ideal for UART wireless communication in electronic projects.

Quantity

The BC-04 Bluetooth module (compatible with HC-05) is a compact solution for serial wireless communication using the Bluetooth V2.0 protocol. Based on the CSR BlueCore4 chipset, it enables data exchange between a microcontroller and a host device (smartphone, computer, GPS) without requiring complex hardware stacks.

Operating in slave mode by default, this module can be configured via AT commands to adjust baud rates, change the device name, or switch to master mode. It is widely used for remote data collection, home automation, and adding wireless connectivity to Arduino or ESP32 projects.
