• Level Shifter board compatible with Arduino Uno interface

  • The STM Nucleo family of development boards have implemented an Arduino Uno R3 pinout to allow a wide range of interface shields to be connected to an STM32 processor. However, the Nucleo boards only expect a 3.3V level on the IO pins. This means that only shields with 3.3V interfaces can be used directly. This product is an adapter board that provides bi-directional level shifters on all the digital pins (using TXS0104 devices) and a potential divider from 5V to 3.3V range on the analogue inputs.
