Overview

This reference design features an evaluation module for the 24-port PSE system which contains a hardware kit, a system firmware image, and a system firmware GUI. The hardware kit consists of a motherboard (PSEMTHR24EVM-081), MSP430 daughtercard (PSEMCUDAUEVM-082) or MSPM0 daughtercard (PSEM0DAUEVM-018), and a PSE daughtercard (TPS23881EVM-083). To evaluate the system (both hardware and software), USB2ANY and MSP-FET adapters are also needed. This guide has been revised to reflect hardware design using the new MSPM0G1107 MCU for multiport PoE systems.

Features
  • Onboard power monitoring
  • 24 4-pair port system, and expandable to 48 port system
  • Highly flexible system with configurable GUI and selectable host interface (I2C or UART)
  • Multiport power management
  • Multiple power supplies
  • Supports legacy powered devices (PDs)
General-purpose MCUs
MSPM0G1107 — 80MHz Arm® Cortex®-M0+ MCU with 128KB flash 32KB SRAM 2x12-bit 4Msps ADC, op-amp
