NINA-B40 Series Stand-alone BLE Modules

u-blox NINA-B40 Series Stand-alone BLUETOOTH^® Low Energy (BLE) Modules are small devices with Bluetooth 5.1 that are particularly suited for harsh professional environments. Additionally, the modules support NFC and IEEE 802.15.4 with Thread and Zigbee. These modules are designed based on the Nordic Semiconductor nRF52833 chip, including an integrated RF core and powerful Arm^® Cortex^®-M4 with an FPU processor. The NINA-B40 modules support the Bluetooth 5.1 direction-finding service with the help of the Angle of Arrival (AoA) and Angle of Departure (AoD) transceivers. These NINA-B40 BLE modules operate at -40°C to 105°C temperature range and 1.7V to 3.6V on a single supply voltage range. This supply voltage can be used as an I/O reference level and easily integrated into simple, single-voltage rail systems. The NINA-B40 modules feature M4F MCU, 128kB RAM, 512kB flash, Bluetooth mesh, and 20 maximum Bluetooth connections.
