6 Arduino Uno Shield Connectors
The GR5515 SK Board provides standard Arduino Uno Shield Connectors, and the connector locations on the SK
printed circuit board (PCB) comply with Arduino standards. You can connect peripherals, such as G-sensor and
heart rate sensor, through Arduino Uno Shield Connectors.
