u-blox NINA-B1 Series Stand-alone Bluetooth® Low Energy (BLE) Modules are small devices that feature Bluetooth 5.0, a powerful Arm® Cortex®-M4 with FPU, and state-of-the-art power performance. The modules are designed with the embedded low power crystal that minimizes the power consumption thus extending the battery life. These NINA-B1 modules are delivered with u-connectXpress software that provides support for u-blox BLE serial port service, GATT client and server, beacons, and NFC™. The BLE modules offer full flexibility to add the application and run on the built-in Cortex-M4 with FPU. These NINA-B1 modules feature M4F MCU, 64kB RAM, 512kB flash memory, Bluetooth mesh, and 7 to 20 maximum Bluetooth connections. The NINA-B112 module comes with an internal antenna whereas the NINA-B111 module has a pin for use with an external antenna. This internal PIFA antenna is specifically designed for the small NINA-B1 form factor. The antenna also provides an extensive range of more than 300m and is independent of a ground plane and component placement. These BLE modules are globally certified for use with the internal antenna or a range of external antennas. The NINA-B1 BLE modules support UART, SPI, PDM and PWM, I2C, I2S, GPIO pins, and AD converters interfaces. These modules operate at -0.3V to 3.9V supply voltage and -40°C to 85°C temperature range. https://elecena.pl/product/17355689/u-blox-nina-b111-04b-stand-alone-ble-module 2020-12-29 https://elecena.pl/product/17355689/u-blox-nina-b111-04b-stand-alone-ble-module 2021-01-19 https://elecena.pl/product/17355689/u-blox-nina-b111-04b-stand-alone-ble-module 2021-03-07 https://elecena.pl/product/17355689/u-blox-nina-b111-04b-stand-alone-ble-module 2025-03-24
