The SparkFun NINA-B306 Thing Plus offers a unique combination development platform in the Thing Plus form factor featuring the NINA-B306 from u-blox™, the ISM330DHCX 6DoF IMU from STMicroelectronics™ and the BME280 atmospheric sensor from Bosch Sensortec™.

The NINA-B306 is a combination Bluetooth® 5 compliant module with an Arm® Cortex®-M4 processor. The NINA-B306 features an integrated PCB antenna removing the need for any external antenna. It includes 1MB Flash and 250kB RAM.

The BME280 combined humidity and pressure sensor measures barometric pressure, humidity, and ambient temperature in a small package. The sensor measures pressure from 300 to 1100hPa and has a full temperature accuracy range from 0 to 65°C. The sensor communicates with the NINA-B306 over I2C.

The ISM330DHCX 6DoF IMU is a high-performance 3D digital accelerometer and 3D digital gyroscope tailored for Industry 4.0. The IMU has full-scale, user-selectable acceleration ranges of ±2/±4/±8/±16g and wide angular rate ranges of ±125/±250/±500/±1000/±2000/±4000dps. The ISM330DHCX has embedded features including Machine Learning Core, programmable FSM, FIFO, sensor hub, event decoding, and interrupts.

The NINA-B306 Thing Plus includes

Qwiic

and

LiPo

battery connectors, and a selection of GPIO, Analog, and communication pins (UART, SPI, and I2C) broken out to the PTH headers. The board also features the MCP73831 single-cell LiPo charger and the MAX17048 fuel gauge to charge and monitor a connected battery. Lastly, we’ve included a

µSD card

slot for external memory needs.
