NerO - Reference design for an Arduino UNO compatible board

Reference design for an Arduino UNO compatible board based on the FTDI FT231X USB UART

The Nero is a reference design for an energy efficient Arduino UNO compatible board based on the ATMEGA328 with the FTDI FT231X USB UART, capable of operating at 5V with a full 1A while remaining cool to the touch.

There are 3 type of modules for selection:

  • NerO-LP1, with 2.54mm pitch female header with long shield pins
  • NerO-SP1, with 2.54mm pitch female header with short shield pins
  • NerO-NP1, with spare shield pins but not mounted. (Provide long shield pins externally.)

Key features:

  • Hi-Speed USB to one-wire interface converter
  • Micro USB connector
  • Status and PWR LEDs moved to edge of PCB - and remain visible when a shield is placed on the expansion connectors
  • On-Off Switch for added user convenience
  • FTDI FT231X USB UART
  • 5V Switching regulator vs LDO regulator
  • FCC/CE certified
