Waveshare Core51822 nRF51822 BLE 4.0 Module

Description

The Waveshare Core51822 module is a compact, fully-featured development board centered on the Nordic Semiconductor Semiconductor nRF51822 System-on-Chip (SoC). This SoC integrates a capable ARM Cortex-M0 processor with a robust 2.4GHz multiprotocol radio transceiver, supporting Bluetooth Low Energy 4.0. It is engineered for ultra-low-power (ULP) wireless applications, offering programmable RF output power and advanced power management to maximize battery life in portable devices.

Architecturally, the module provides independent development paths for the application firmware and the BLE protocol stack, offering flexibility for developers. It includes hardware-accelerated 128-bit AES encryption for secure communications and a Programmable Peripheral Interconnect (PPI) system for efficient, low-latency peripheral interaction without CPU intervention. The onboard PCB antenna eliminates the need for external RF components, simplifying integration.
