1. Overall Introduction
Raytac’s 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 of the module:
1. Dual Transmission mode of BLE & 2.4Ghz RF upon customer 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 consumption.
4. Be compatible with a large installed base of mobile phones, tablets and computers.
5. Fully coverage of BLE software stack. See 1.3 Profile & Service Information.
6. BLE & RF transmission switching helps products fit all operation system and most
hardware.
