TIDM-TM4C129POE

TM4C129POE Power Over Ethernet (PoE) Reference Design for Connected IoT

TIDM-TM4C129POE

Design files

Overview

This design integrates Texas Instruments PoE solutions with TM4C129x high performance microcontrollers to enable customers to develop applications for IoT in a small form factor board. Ability to derive power over existing network cable with intelligence to gather, process and exchange data with the cloud increases the value of the end application.

Features
  • Small form factor board measuring 4.95” by 3.45” with TM4C129ENCPDT microcontroller featuring Integrated Ethernet PHY and MAC
  • Integrated RJ45, Transformer and Diode bridge for PoE power stage for lower BOM cost
  • 7W isolated output from the fly-back converter, with provision for both 5V and 3.3V
  • Dual booster pack headers to prototype end applications with a wide range of booster packs from TI and third-party
  • Optional power header to supply external DC power from UPS in case of a network power failure


A fully assembled board has been developed for testing and performance validation only, and is not available for sale.
