描述 Description

Arduino? Nano 33 BLE is a miniature sized module containing a NINA B306 module, based on Nordic nRF52480 and containing an Arm?

Cortex?-M4F and a 9-axis IMU. The module can either be mounted as a DIP component (when mounting pin headers), or as a SMT

component, directly soldering it via the castellated pads.
