2.3 Header Information

J17 Aardvark Connector and J15 I2C Selection Jumper

This connector is configured to allow the Total Phase Aardvark to connect directly to the EVM. One or more I2C bus can be connected to the Aardvark connector by connecting jumpers on J15. When making this connection, both the SCL1/2/3 and SDA1/2/3 must be selected by installing the jumper.

  • I2C1 is connected to the I2C controller of the TPS25772-Q1

  • I2C2 connects to I2C2 of the TPS25772-Q1 (dependent on EVM configuration) and the TIVA MCU

  • I2C3 connects to the TIVA MCU
