MDBT42Q BLE Module

Uniden UM725GBT Bluetooth single module

Raytac’s MDBT42Q-U is a BT 4.2 and BT 5 stack (Bluetooth low energy or BLE) module designed based on Nordic nRF52832 SoC solution, which incorporates: GPIO, SPI, Ua I2C, I2S, PWM, ADC and NFC interfaces for connecting peripherals and sensors.

Features of the module:

1.    Dual Transmission mode of BLE & 2.4Ghz RF upon customer’s preference.

2.    Compact size with (L) 16 x (W) 10 x (H) 2.2 mm.

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

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

5.    Fully coverage of BLE software stack..

6.    BLE & RF transmission switching helps products fit all operation system and most hardware.
