Solderless Breadboard


36 V maximum, per connection point


1 A maximum, per connection point


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.


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.
