Description
nRF51822-CEAA-R7 is a Bluetooth Low Energy (BLE) System-on-Chip from Nordic Semiconductor (nRF51 family). It combines a 32‑bit ARM Cortex‑M0 MCU, a 2.4 GHz BLE radio, embedded flash and RAM in one chip, enabling compact, battery-powered wireless devices. Typical specs include a Cortex‑M0 core up to 16 MHz, about 256 KB flash and 32 KB RAM, plus GPIOs and common peripherals (serial interfaces, PWM, timers, etc.). It’s designed to run with Nordic’s SoftDevice BLE stack and the Nordic SDK for firmware development, optimizing power efficiency for beacons, sensors, wearables, and control devices.
CEAA-R7 denotes the device’s packaging/temperature code (CEAA) and the silicon revision (R7). For exact pinout, electrical specs, and operating ranges, consult the nRF51822 datasheet and product page.
