Welcome Here  Shenzhen Mingjiada Electronics Co., Ltd.

The NRF52833-QIAA-B-R7 is a general purpose multi-protocol SoC with Bluetooth direction finding and can operate over a temperature range of -40°C to 105°C.

It is the 5th product in the industry leading nRF52 family and is built around a 64 MHz Arm Cortex-M4 FPU platform with 512 KB Flash and 128 KB RAM for higher value applications.

The higher 105°C operating temperature limit, combined with support for large amounts of memory and dynamic multi-protocols, ensures that the nRF52833 is an ideal device for a variety of commercial and industrial applications, including professional lighting and asset tracking. nRF52833 features a 1:4 RAM to flash ratio and +8 dBm output power, making it suitable for advanced wearables or smart home applications requiring robust coverage. applications requiring robust coverage.

The NRF52833-QIAA-B-R7 includes a range of analogue and digital interfaces such as NFC-A, ADC, full-speed 12 Mbps USB 2.0, high-speed 32 MHz SPI, UART/SPI/TWI, PWM, I2S and PDM, and has a wide input voltage of 1.7-5.5 V. It can be powered via rechargeable battery or USB. It features a two-stage LDO regulator and DC-DC converter, which together with the automatic power management system, can help achieve low power consumption even in more advanced applications.
