24-Port (2 pair) Power Sourcing Equipment Reference
Design for Multi-port Applications
Description
This reference design features an evaluation module
for the 24-port (2 pair) PSE system which contains a
hardware kit, a system firmware image, and a system
firmware GUI. The hardware kit consists of a mother
board (PSEMTHR24EVM-081), an MSP430 daughter
card (PSEMCUDAUEVM-082), and a PSE daughter
card (TPS23882EVM-084). To evaluate the system
(both hardware and software), USB2ANY and MSP-
FET adapters are also needed.
The MSP430F5234 on PSEMCUDAUEVM-082 has
been programmed with pre-production firmware for
EVM testing purposes. Please follow the instructions in
this user's guide to flash the latest firmware from
before evaluation.
