Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | GND | power_in | Ground pin, grouped with the PAD1 exposed pad as the ground connection. |
| 2 | GND | power_in | Ground pin, grouped with the PAD1 exposed pad as the ground connection. |
| 3 | GND | power_in | Ground pin, grouped with the PAD1 exposed pad as the ground connection. |
| 4 | NC | unconnected | Listed as No Connected in the pin table; the layout note says this pin is connected to VIN or GND for easy layout. |
