3.1.1 Hardware

The following hardware is required to get started with the reference design:

  • PSEMTHR24EVM-081: motherboard for 24 port PoE PSE applications (sold separately)
  • PSEMCUDAUEVM-082: MSP430 daughtercard for 24 Port PoE PSE applications (sold separately)
  • TPS23882EVM-084: TPS23882 daughtercard for 24-port Type 3 (2 pair) PoE PSE applications (sold separately)
  • USB2ANY interface adapater: used with PSE system firmware GUI for I2C/UART interaction with PSEMCUDAU-082 daughtercard (sold separately)
  • MSP-FET programmer: used with the Uniflash GUI for programming the MSP430 device
