Using With Arduino

 

PTHAT Direct Serial/I2C Connection.

The PTHAT has been designed primarily to fit and work with the Raspberry Pi, it can also be used with other MCUs such as the Arduino Boards.

We have several diagrams below showing how to connect the PTHAT with various popular Arduino boards via Serial or I2C. At the moment the firmware only supports Serial communications but the I2C may be used for future firmware updates or for developers that which to use it.

Connecting Serial/I2C Board to Arduino

You can also connect the Arduino boards to the PTHAT using the Serial/I2C Board that can be found on the Stand Alone usage page.

If using the Serial/I2C board you will notice that you only have to supply 5 Volts and also need to set the jumpers to choose Serial communications or I2C.
