1. Overall Introduction
Raytac’s MDBT42 & MDBT42-P 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) 13.8 x (W) 8.8 x (H) 1.9 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.
