Overview

BOOST-PSEMTHR-007 is the base board for the TPS23880 and TPS23881 PSE controllers. This board contains four 2-pair ports that can be used to send up to 30W/port for IEEE 802.3at applications and two 4-pair ports that can be used to send up to 90W/port for IEEE 802.3bt applications.

Features
  • Four IEEE802.3bt ready, 2 pair ports with 1000BASE-T (gigabit Ethernet data pass through)
  • Two IEEE802.3bt ready, 4 pair ports with 1000BASE-T (gigabit Ethernet data pass through)
  • On board I2C interface to TPS23880 or TPS23881 devices from either USB2ANY or MSP430FR5969 LaunchPad development kit
  • Single DC power supply input, on board 3.3V regulator, port ON status LEDs and user test points
