The number of ground connector pins on an Arduino board depends on the specific model, but here are the details for a few common Arduino boards:
1. **Arduino Uno**:
- The Arduino Uno has three ground (GND) pins. They are typically labeled as **GND**.
2. **Arduino Mega**:
- The Arduino Mega has several ground pins, typically labeled as **GND**, and there are 5 GND pins available on the board.
3. **Arduino Nano**:
- The Arduino Nano has two ground pins, labeled as **GND**.
4. **Arduino Leonardo**:
- The Arduino Leonardo has three ground pins, labeled as **GND**.
For most Arduino boards, the GND pins are usually easily accessible along the edges of the board, allowing for convenient grounding when connecting peripherals and components. For precise information, it is always recommended to check the specific datasheet or schematic of the model you are using.
