Welcome Here  Shenzhen Mingjiada Electronics Co., Ltd.

Mingjiada Electronics has been supplying NRF52840-QIAA - a high-performance wireless SoC (System-on-Chip) with multi-protocol concurrency support.NRF52840-QIAA is based on ARM Cortex-M4F core, with up to 64MHz, integrated 1MB Flash and 256KB RAM, supporting Bluetooth 5.4, Thread, Zigbee, IEEE 802.15.4, etc. It is suitable for Internet of Things (IoT), smart home, IoT. 256KB RAM, supports Bluetooth 5.4, Thread, Zigbee, IEEE 802.15.4 and other wireless protocols, and is suitable for Internet of Things (IoT), smart home, industrial automation and other scenarios.

The core advantage of the NRF52840-QIAA is its dynamic multi-protocol support, which allows it to run multiple wireless protocol stacks at the same time, such as Bluetooth + Zigbee or Bluetooth + Thread, which greatly enhances the flexibility of device interconnection. In addition, the NRF52840-QIAA is available in a 73-QFN package (7×7mm) with an operating voltage range of 1.7V~5.5V for battery-powered devices and meets industrial-grade temperature standards (-40°C~+85°C).

NRF52840-QIAA Core Features

Concurrent multi-protocol support

NRF52840-QIAA can run Bluetooth 5.4, Zigbee 3.0, Thread and other protocols at the same time, which is suitable for smart home gateways, industrial sensor networks and other applications that require multi-protocol co-operation.

It supports dynamic protocol switching and can adapt to different wireless standards without reconfiguring the hardware.

High-performance Processing
