MDBT42Q is a BT 4.0, BT 4.1 and BT 4.2 stack (Bluetooth low energy or BLE) module designed based on Nordic nRF52832 SoC solution, which incorporates: GPIO, SPI, UART, I2C, I2S, PWM and ADC interfaces for connecting peripherals and sensors.

Features

Dual Transmission mode of BLE & 2.4 GHz RF upon customer preference.

Long working distance: over 80 meters in open space

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

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

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

Fully coverage of BLE software stack. See 1.3 Profile & Service Information.

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