u-blox NINA-B41 Series BLUETOOTH® 5.1 Low Energy Modules are based on the Nordic nRF52833 chip and are pin-compatible with the NINA-B3 module. This series features NINA-B416, NINA-B411, and NINA-B410 modules. The NINA-B416 module is equipped with an integrated antenna on the module that will simplify the integration, as there will be no need to do an RF trace design on the host PCB. The NINA-B410 is equipped with a U.FL connector that connects the external antenna to the module. These modules operate at the -40°C to 105°C temperature range and 1.7V to 3.7V supply voltage range.
