Welcome Here  Shenzhen Mingjiada Electronics Co., Ltd.

The nRF52811 Bluetooth® 5.2 Direction Finding SoC takes full advantage of the latest and most powerful features of Bluetooth 5.2. These features include direction finding, which takes Bluetooth positioning to a new level. The devices are powered by a 64MHz Arm® Cortex™-M4 CPU. The devices are equipped with a variety of digital peripherals including PDM, PWM, UART, SPI and TWI. nRF52811 also features a powerful 12-bit ADC. The devices use an advanced on-chip adaptive power management system to achieve extremely low power consumption.

The radio in the nRF52811 SoC has comprehensive protocol capabilities, including Bluetooth® 5.2 direction finding, all Bluetooth® 5.2 features, 802.15.4, Thread, Zigbe, ANT and 2.4GHz proprietary protocols. With 4dBm TX power, the device is optimised to provide optimal RX sensitivity for all SoCs in the nRF52 family:

- Bluetooth Low Power - Long Range: -104dBm

- Bluetooth Low Power - 1Mbps: -97dBm

- 802.15.4 (Thread/Zigbee): -101dBm

• 1.Is the inventory and price seen on the platform accurate?

  A: all online goods on the shelves can be ordered online, but considering the large liquidity of spot inventory, it is not possible to achieve 100% accuracy at present. In case of any abnormality, you can contact our company online and give the corresponding solution.

• 2.Are all our products genuine?

  A: our self-supporting products are from cooperative domestic and foreign original factories or authorized agents, and the source can be traced to ensure the original and authentic products.

• 3.Can you provide the qualification certificate of the original factory or agent?

  A: at present, our self-employed brands TI，ST，ADI，NXP，LATTICE，CYPRESS，INFINEON，XILINX and other first-line brands. Other channels are the original factory and agency channels. If necessary, we can communicate and confirm according to the specific brand and model.

• 4.Can I make an inquiry through the company's website?

  A: You can inquire through the website, or by phone and email.

• 5.When can I deliver the goods after placing an order? How long will it take to get there?
