      MDBT40 is a BT 4.0 & BT 4.1 stack (Bluetooth low energy or BLE) module designed based on Nordic nRF51822 SoC solution, which incorporates: GPIO, UART, I2C, SPI, PWM and ADC interfaces for connecting peripherals and sensors.


      1. Dual Transmission Mode of BLE & RF 2.4G upon customer preference. 

      2. Compact size with (L) 18 x (W) 10 x (H) 3.2 mm 

      3. Low power requirements, ultra-low peak, average and idle mode power consumption. 

      4. Compatible with a large installed base of mobile phones, tablets and computers. 

      5. Fully coverage of BLE software stack including: 

          Proximity Profile; Heart Rate Profile; Health Thermometer Profile; 

          Blood Pressure Profile; Running Speed & Cadence Profile; 

          HID Over GATT Profile; Alert Notification Profile; Glucose Profile; 

          Cycling Speed & Cadence Profile 

      6. BLE & RF transmission switching may help products to fit all operation system 

      7. BLE & RF transmission switching may help products fit all kinds of hardware.
