Bluetooth LE 4.2+NFC module/eval board, in distribution
Distributor Alpha Micro has u-blox’s NINA-B111 and B112 modules and their evaluation kit, EVK-NINA-B1; these are Bluetooth low energy 4.2 compliant devices, aimed at IoT developments

u-blox’ NINA-B112 systems combine an embedded ARM Corex M4F MCU and Bluetooth stack with antenna and radio transceiver, suiting connected sensors and actuators in building automation, medical devices, telematics and monitoring/control systems. NINA-B111 is identical but has a connector for an external antenna. An NFC (near field communications) capability has also been integrated to enable a simplified pairing process. GPIO, ADC, I ²C, SPI and UART interfaces allow connections for sensors, accelerometers, LEDs and control devices directly to the module.


Two evaluation board variants are available. Both the EVK-NINA-B111 and EVK-NINA-B112 include connectors to power the board through USB, coin cell battery or an external supply, an NFC antenna and onboard debugger hardware and firmware. The EVK-NINA-B112 also includes the onboard Bluetooth antenna.

The modules integrate onboard power management for current consumption of 400 nA, with wake up on an external event. This increases to 2 µA during idle state, and 5 mA (at 0 dBm at 3.0 VDC), during transmission.


An enhanced connection security capability meets the security features of Bluetooth version 4.2, delivering IPv6 and a faster throughput versus previous generations. NINA modules are designed to support the future Bluetooth 5.0 specification via an over-the-air firmware upgrade and includes 512 kB Flash and 64 kB RAM for this function.
