Description

This reference design is a fully functional development board powering an NXP™ i.MX 6ULL application processor from a TPS6521815 PMIC. The hardware design consists of DDR3L SDRAM (512 MB), 32-MB Serial NOR Flash, 8-GB eMMC 5.0 iNAND, SD Card interface v3.0, dual-channel 100Base-T Ethernet, 5-channel USB hub with Type-A ports, micro-AB USB OTG, mountable LCD screen, and expansion connector for additional inputs and outputs.

This design is intended to be used as a reference for data concentrator projects in grid communications or for any project using the i.MX 6ULL, i.MX 6ULZ, or i.MX 6UltraLite processor that requires evaluation of alternative power solutions.

Features
  • Full system-on-board for rapid development of NXP i.MX 6ULL, i.MX6 ULZ, and i.MX 6UltraLite systems
  • Low-power modes and DVFS supported
  • Ethernet, USB wired connectivity
  • LCD display included for real-time current monitoring of 6-channels
  • Selectable boot options (SD, eMMC, QSPI)
