The MDBT53-1M Bluetooth 5.2 module is designed for engineers who need reliable, low-power wireless connectivity in a compact footprint. Based on a dual-core nRF5340 device with Cortex-M33 application and network cores, it delivers both real-time radio control and powerful application processing on a single module.
With integrated flash and RAM on each core, plus a chip antenna and 48 GPIOs, it provides a flexible platform for connected products without the complexity of RF design. The module supports Bluetooth Low Energy, Bluetooth mesh, Bluetooth Direction Finding, Bluetooth low energy audio, ANT+, Zigbee and Thread over IEEE 802.15.4, making it suitable for many protocol stacks and ecosystems.
Its wide operating temperature range from -40 to +105 °C suits harsh industrial and automotive-adjacent environments. Multiple serial, audio and analogue interfaces – including SPI, QSPI, UART, I²C, I²S, PWM, ADC, NFC and USB – make it easy to attach sensors, actuators and host processors. The MDBT53-1M integrates the RF front end, chip antenna and regulatory approvals to shorten development time and simplify global certification for production designs.
