    Solderless Breadboard

    Voltage

    36 V maximum, per connection point

    Current

    1 A maximum, per connection point
    spd-note-notice
    Notice  

    Exceeding the current or voltage ratings of a solderless breadboard connection can result in damage to the breadboard. For higher currents, especially for power and ground connections, use multiple connection points to share the current load.

    spd-note-notice
    Notice  

    NI recommends the use of both connection points of the Fixed User Power Supplies to distribute power. For example, when supplying +5 V at 2 A to your circuit, use both connection points provided on the solderless breadboard strip so that each connection point only supplies up to 1 A, maximum. Use at least an equal number of ground connections for each connection.
