The module is powered by a Nordic nRF52832 system-on-chip (SoC), which contains a 32-bit ARM Cortex-M4F processor with 512kBytes of flash memory and 64kBytes of RAM. The Nordic SoC also includes a 12-bit analogue-to-digital converter and support for SPI, UART, I2C, and I2S interfaces.
The EYSHSNZWZ integrates a high-performance PCB antenna, 32 MHz system clock, and support for NFC-A Type-2 for touch-to-pair applications.
It offers typical output power of +4dBm, and works in the low-power 2.4 GHz ISM band.
RoHS-compliant, the module is FCC, IC, and MIC certified and is ideal for low-power wireless applications, such as wearables, heart rate and blood pressure monitors, thermometers, and mobile accessories.
