BDE-BLEM201 Bluetooth 5.0 Low Energy Module
Product Information:
The BDE-BLEM201 is a Bluetooth 5.0 low energy module that is
compliant with the Bluetooth 5.0 single-mode. It supports both
master and slave modes, allowing for 3+ simultaneous connections in
master mode. The module integrates a Bluetooth Low Energy stack,
eliminating the need for an external MCU. It offers excellent RF
performance with a communication range of 100m (LOS). The module
features an ultra low power 8051 microcontroller core, 8K RAM with
retention, and 256K in-system-programming flash. It also includes
23 GPIOs, a 12-bit ADC with eight channels and configurable
resolution, and data interfaces such as I2C and USART. The
BDE-BLEM201 module has a chip antenna with -0.5 dBi Gain and comes
in two sizes: 16.55mm x10.88mm x 1.5mm (Without Shielding) and
16.55mm x10.88mm x 2.2mm (With Shielding). It is BQB certified and
compliant with FCC, CE, and RoHS standards.
Product Usage Instructions:
- Step 1: Module Integration
Integrate the BDE-BLEM201 module into your product by following
the recommended module location in the X-Y plane as shown in Fig.
4. It is advised not to place the module in the locations shown in
Fig. 5. - Step 2: Power Supply

BDE-BLEM201 module. Connect the required GPIOs, I2C, USART, and
other interfaces as per your application requirements. - Step 4: Data Transfer
Use the integrated Bluetooth Low Energy stack to establish
connections with other devices. The module supports master and
slave modes, allowing for simultaneous connections in master mode.
Utilize the provided data interfaces (I2C and USART) for data
transfer. - Step 5: Compliance and Certification
Ensure that your product complies with FCC, CE, and RoHS
standards as the BDE-BLEM201 module is already certified for these
standards. - Step 6: Application Examples
The BDE-BLEM201 module is suitable for various applications
including medical devices, sports and fitness equipment, home
electronics, mobile and PC accessories, and industry automation.
Customize the module’s functionality to meet the requirements of
your specific application.
