Bluetooth Interface Module

Product catalog summary

Product Overview
The Bluetooth Interface Module facilitates communication between a CPU board and Bluetooth-enabled devices, allowing file and command transfers. It is based on the SPBT2632C2A Bluetooth module and includes a DB9 connector and a 6-pin header for interfacing. The module is designed for academic project development and includes 7 GPIO pins for controlling external devices like LEDs and relays.

Technical Specifications

Bluetooth Module: SPBT2632C2A.AT2
Operating Voltage: 3.3V
Input Voltage: 5V
Current Consumption: 30mA
Flash Memory: 256kb
RAM: 48kb
GPIOs: 7

Interface Details
The module includes a 6-pin header for CPU interface and a DB9 connector for PC communication. The 6-pin header supports transmit and receive signals along with handshaking signals (RTS and CTS). The DB9 connector is RS-232 compatible and used for software updates and CPU board interfacing.

Power
The module can be powered via an external 5V AC to DC adapter or directly from the CPU board using a power cable. A 2.5mm power jack and a 4-pin connector are provided for these purposes. A reset switch and an LED indicator for 3.3V power are included.

Memory and I/O
The module features 256kb of flash memory and 48kb of RAM. It offers multiple communication options with the CPU and PC, and includes 7 GPIOs that can be configured as input or output.

Communication
Designed for serial communication, the module uses standard UART signals for data transfer between the board and PC, with CTS and RTS for synchronization. It enables data transfer from Bluetooth-enabled devices to the CPU board.

Physical Characteristics
The module measures 65mm x 45mm and includes four mounting holes for attachment to surfaces or cases.

Reference Schematics
The document includes detailed schematics for power regulation, reset functionality, and connectivity options, illustrating the module's design and component layout.
