- Accelerometer Development Board
- I2C Line: 3.3-15V
- 2 Interrupt Lines
The GPSv1.0 is provided as a wide input range Accelerometer development board. Most development environments provide a 3.3V output but sometimes utilize higher voltage I/O lines (Arduino is 5V I/O, Raspberry Pi is 3.3V I/O). This board can support any voltage I/O lines up to 15V.
