3.3 Fusion Power

The Fusion board can be operated as stand-alone, or connected and mounted to the EVM. There are two different power connectors:

  • One for power from the TDA2Px and TDA4x EVMs only (J40)
  • One for a power source similar to a car battery, with circuitry to drop down the voltage for the Fusion board (J14)

The connector (J40) that is used for power when connected to the TDA2Px and TDA4x EVMs has an included adapter in the Fusion box. It is important to not the cable between the TDA2Px and the TDA4x EVMs are different, so ensure the correct cable is used. The Fusion is powered specifically from the EVM. The 12-V power pins on the CSI-2 connector have been disconnected due to current limitations, hence the need for a separate power connector.

There is also the stand-alone aspect of the Fusion board. However, for these use cases, there is a different power connector (J14) that must be used. The J14 connector is used and provides the circuitry to regulate input voltage from a separate power source. Pay special attention to the connector that is being used as improper use can damage the board.
