I2C buses on Jetson TK1

There are six I2C buses available on Tegra K1, and four are made available on the expansion header.

  • GEN1_I2C (1.8V) on (2x25) J3A1 50-pin expansion port and J3A2 (3x25) 75-pin expansion port
  • GEN2_I2C (3.3V) on (2x25) J3A1 50-pin expansion port
  • PWR_I2C (1.8V) on (3x25) J3A2 75-pin expansion port
  • CAM_I2C (3.3V) on (3x25) J3A2 75-pin expansion port
