Bluetooth Low Energy 5.0 SiP module, nRF52832-based, 6.5 x 6.5 x 1.15 mm 52-pad package with optional internal or external antenna The ANNA-B112-01B is an ultra-compact, stand-alone Bluetooth® Low Energy (BLE) 5 module developed by u-blox. It is built around the Nordic nRF52832 SoC, which integrates a powerful Arm Cortex-M4 processor with FPU, RF circuitry, memory, and antenna in a single System-in-Package (SiP). This module is designed for industrial and IoT applications, offering a combination of high performance, low power consumption, and small size. It supports both host-controlled operation (AT commands via u-connectXpress) and standalone embedded applications (open CPU mode), giving designers flexibility in system architecture. 🔑 Key Features 🧠 Processing & Memory 64 MHz Arm Cortex-M4 CPU with FPU 512 KB Flash and 64 KB RAM Supports open CPU (run user firmware directly on module) 📡 Wireless Connectivity Bluetooth 5.0 (BLE) compliant Supports: GATT client & server Bluetooth mesh Simultaneous central + peripheral roles Data rate up to 2 Mbps 📶 RF & Antenna Operates at 2.4 GHz ISM band Integrated chip antenna Optional external antenna via antenna pin Range up to ~160 m (internal antenna) 🔌 Interfaces & Peripherals Communication interfaces: UART, SPI, I²C, I²S Additional features: ADC (12-bit) PWM, PDM Up to 25 GPIOs Supports NFC (for pairing / data) ⚙️ Software & Development Comes with u-connectXpress firmware: AT command interface Serial Port Service (SPS) Easy integration without deep BLE stack knowledge Supports development using: Nordic SDK Arm Mbed Supports FOTA (Firmware Over-The-Air updates) 🔋 Power & Electrical Supply voltage: 1.7V to 3.6V Optimized for low-power applications Sleep current as low as ~300 nA 📦 Physical Characteristics Ultra-compact size: 6.5 × 6.5 × 1.2 mm Package: 52-pin SMD module Operating temperature: –40°C to +85°C 🌍 Certifications Globally pre-certified (FCC, CE, etc.) Reduces time and cost for product certification
