DL-N52832 is a Bluetooth module with small size and low power consumption specially designed for data transmission. The module adopts the nRF52832 radio frequency chip imported from NORDIC, which supports Bluetooth 4.2 and Bluetooth 5.0, the chip comes with high-performance ARM CORTEX-M4 core, and has rich peripheral resources such as UART, I2C, SPI, ADC, DMA, PWM, etc. It includes all the IO ports of nRF52832, which is convenient for multi-functional development.
Compare with mainstream brands on the market (such as TI, Freescale, Siliconlabs, Cypress, and Dialog), nRF52832’s technical advantages are prominent, which is obviously the leader in this regard, the first choice for IOT applications.
* It has better power consumption performance: most chips consume 5mA-8mA, while nRF52832 consumes 4.6mA-5mA;
* It has better RF performance: RF output 4dBm, sensitivity -96dBm;
* It has stronger processing capabilities: ARM CORTEX-M4F core;
* It has more storage resources: large-capacity Flash is 512KB; RAM is up to 64KB;
* It has more powerful multi-protocol support: BLE, ANT, 2.4GHz Proprietary, NFC
But please note that: the DL-N52832 module is a hardware platform. There is no program by default at the factory, and users need to carry out secondary development. The antenna output is optimized by professional antenna engineers, and the module has maximized the RF performance of the chip.
