NRF52 series -- nRF52832 strikes, and nrf52nrf52832 strikes
NRF52 series -- nRF52832 attack
With decades of development in wireless technology, Nordic has launched the first μblue chip, nRF8001. Its low power consumption and other features attracted the attention of countless manufacturers at that time, and applied this product to multiple fields. After that, it launched the ultra-low power wireless SoC nRF51 series, taking advantage of its high integration, performance, flexibility, and the ease of use of embedded protocol stack to develop wireless applications on the SoC, Bluetooth wireless applications are easy to use. In June 2015, Nordic launched its next-generation super-low-power wireless solution, the first product of the nRF52 series, nRF52832, the nRF52832 is equipped with a 64 MHz ARM Cortex-M4F processor, with a 512kB flash memory and 64kB RAM, On-Chip RF Balun, and added with NFC features, lower power consumption and higher performance.
