Breadboard PSU 5V/3.3V 1A

This breadboard power supply is a companion module, which provides 5V, 3.3V to rails on a solderless breadboard. It is an extremely useful facility, which provides regulated voltage rails for project circuits. The module design is in the form of a plug-in, which connects onto the breadboard. This module has a regulated 5V USB output through to power other USB devices (your Arduinio boards), which can be extremely useful. It can switch the power between 5V and 3.3V to the rail of a breadboard. Each rail has a self switcher of 5V/3.3V/OFF. There is no need to disconnect the power jack as each rail can be switched between 5V/3.3V/OFF. More powerful Voltage Regulators (LDO) have been used for guaranteed 1A output to 5V and 800mA to 3.3V (big current for WI-FI projects) short circuit and overheating protection input diode to protect circuitry from negative voltages or AC power supplies. It also has a LED power indicator.

Recommendations for use:

  • Use a USB wall adapter, such as one used to charge a cell phone, to power the module
  • The 5V output of the module does not have any overcurrent protection between it and the 5V line of the USB jack, therefore we recommend using wall adapters to power the module through the USB connector because most standard USB wall adapters include built-in overcurrent protection
  • The USB jack can be used as a power output when powering the module though the input barrel jack (ex: you can attach an Arduino's USB cable to the USB jack on the power module and use the power module to power the Arduino); the total cumulative current drawn from the USB jack and the breadboard power rails must not exceed 700mA
  • IMPORTANT: it is not recommended to power the module using a computer's USB port. Any overcurrent or short on the 5V line could potentially damage the computer
