For Arduino DUE

  • Newer Arduino boards like Arduino DUE is only 3.3V tolerant, supplying signals with 5V will destroy the MCU on board
  • And sometime when you need more powerful boards, you choose newer boards like one mentioned above

Pre-requisite:

  1. Starting to play with Arduino

Objectives:

  1. Use newer boards with lower voltage safely

Descriptions:

  1. One bi-directional level shifter by ADA-Fruit:

    8-channel Bi-directional Logic Level Converter - TXB0108

  2. Other solutions:
    Using 4050/74LVX245 as non-instant bi-directional solution.
