Ardbox - Arduino I/Os 5V pins
The Ardbox has some of the Leonardo board pins available. These pins can be programmed
according to Arduino features such as I/Os operating at 5V or any additional features present
in the pins (for example I2C communication in pins SCL and SDA). As this pins are directly
connected to the Arduino Leonardo board they are not as well protect as the normal inputs.
These pins are mainly meant to be used as prototyping.
*IMPORTANT: Do not connect the terminals in the chart above to voltages higher than 5V.
These terminals provide direct access to the Leonardo board.
A part from the switch configuration there are some special conditions depending on these 5V.
Now it is going to be shown the considerations to operate with these pins.
I2C pins – SDA/SCL
The I2C protocol is meant to work in a pull-up configuration. The I2C pins in the Arduino
Leonardo are not pull-up, so in order to work with the I2C an external pull-up resistor is
required. If it is meant to work as a GPIO at 5V, the switches must be set as I2C, (section 8).
These pins are not stablished with a pull-up or a pull-down configuration. The state of these
pins is unknown. If these pins must be used they require a pull-up or a pull-down
configuration. The Arduino board allows the pins to be set in a pull-up configuration. If not it
must be stablished an external pull-up or pull-down circuit in order to correctly work with
these pins.
Pin 2/Pin 3
These pins are only referred to the inputs I0.5/I0.6. If the switch configuration is in OFF
position the pins Pin 2/Pin 3 will be available.
These pins are not stablished with a pull-up or a pull-down configuration. The state of these
pins is unknown. If these pins must be used, they require a pull-up or a pull-down
configuration. The Arduino board allows the pins to be set in a pull-up configuration. If not it
must be stablished an external pull-up or pull-down circuit in order to correctly work with
these pins.
