SparqEE ACCELv1.0

Special Features:

  • 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.

Power

  • Supply: 2.0 to 3.6V (for 3.3V)
  • I/O: 2.0 to 15V

Physical

  • 24mm x 23mm (0.94″ x 0.91″)

Operating Temperature

  • -40°C to +85°C
