Description

This reference design integrates TI's Power over Ethernet (PoE) with the high-performance SimpleLink™ MSP432E4 Ethernet microcontroller (MCU) with Ethernet to enable customers to develop applications for Internet of Things (IoT) in a small form factor board. The design increases the value of the end  application with its ability to derive power over existing network cabling combined with intelligence to gather, process, and exchange data with the cloud.

Features
  • Small  Form Factor Board Measuring 4.95” × 3.45” With MSP432E401Y MCU Featuring Integrated Ethernet PHY and MAC
  • Integrated RJ45, Transformer, and Diode Bridge for PoE Power Stage for Cost-Effective BOM
  • 7-W Isolated Output From Fly-Back Converter With Provision for Both 5-V and 3.3-V Output Power Rails
  • Optional Power Header to Supply External DC Power From UPS in Case of Network Power Failure
  • Dual BoosterPack™ plug-in module headers to Prototype End Applications With Wide Range of BoosterPacks From TI and Third-Party
  • SimpleLink MSP432E4 Software Development Kit (SDK) Examples May be Run Without Modifications for Evaluation
