Waveshare Core51822 (B) nRF51822 BLE 4.0 Wireless Module

Description

The Waveshare Core51822 (B) module is built around the Nordic Semiconductor Semiconductor nRF51822, a highly integrated System-on-Chip (SoC) designed for Bluetooth Low Energy 4.0 and proprietary 2.4GHz wireless connectivity. Its architecture centers on a 32-bit ARM Cortex-M0 CPU, providing efficient processing for embedded applications while maintaining minimal power consumption through advanced sleep modes and a programmable peripheral interconnect (PPI) system.

The integrated 2.4GHz radio supports output power programmable from -20 dBm to +4 dBm, allowing developers to optimize for range or battery life. The module includes hardware-accelerated 128-bit AES encryption for secure data transmission. Its pinout is compatible with the NRF51xxx series and functionally compatible with the popular NRF24L series, easing migration from legacy designs.
