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)
  • PSEM0MCUDAUEVM-018: MSPM0 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)
  • TPS23882B1EVM-035: TPS23882B 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
  • XDS110 Debugger: used with the UniFlash GUI for programming the MSPM0 device
Note: The MSPM0 is recommended for all new FirmPSE designs. The MSP430F5234 on PSEMCUDAUEVM-082 and the MSPM0G1107 on PSEM0MCUDAUEVM-018 are programmed with pre-production firmware for EVM testing purposes. Follow the instructions in this user's guide to flash the latest firmware from TI.com before evaluation.
