Arduino Buyers Guide

Arduino Buyers Guide

The Arduino AT MEGA 2560 R3 is the ‘motherboard’ of the Echo. It is an open source hardware, so you may find ‘clones‘ from different manufacturers – many of these will work fine, if the steps below are followed:

Good Arduino!

  • The Arduino you want is one with a ‘16U2′ chipset – this refers to the USB controller that is located in the circle in the picture.
  • The 16U2 chipset is SQUARE.

Bad Arduino!

  • The Arduino with the CH340 chipset has been known to have serial communication problems – that means that it may not properly communicate with the display.
  • The CH340 chipset is RECTANGULAR – and looks a little like a caterpillar!

Bad Arduino!

  • Any Arduino trying to be “Fancy” with additions or extra selling features.
  • Avoid “WIFI” boards, or “Development” boards.
  • If in doubt, contact us and send over your product link for a second opinion!
