1. Overall Introduction

Raytac’s MDBT50Q, MDBT50Q-1M, MDBT50Q-P1M and MDBT50Q-U1M is a BT 5.0 stack (Bluetooth low energy or BLE) module designed based on Nordic nRF52840 SoC solution, which incorporates: GPIO, SPI, UART, I2C, I2S, PMD, PWM, ADC, NFC and USB interfaces for connecting peripherals and sensors.

Features of the module:

1. Embedded 2.4GHz transceiver supports Bluetooth 5, IEEE 802.15.4 & 2.4Ghz RF & ANT upon customer’s preference.

2. Compact size with (L) 15.5 x (W) 10.5 x (H) 2.2 or 2.0 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.

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