الوصف
The Breadboard Power Supply Module plugs directly into a solderless breadboard and provides 3.3 and 5V power directly to the breadboard power rails.
Features
- Power supply module for breadboard, compatible with 5V, 3.3V
- Applicable to MB102 breadboard
- Input voltage: 6.5-10V (DC) or USB powered
- Output voltage: 3.3V or 5V, switchable
- Maximum output current: less than 500ma
- Two independent channel control, can be switched to 3.3V, 5V
- Onboard 3.3V, 5V DC output pins
Install Module On Breadboard
The module plugs into one end of a standard breadboard.
Be sure to insert the module into the correct end of the solderless breadboard so that the +/- on the module line up with red/blue lines on the breadboard as shown here. The ‘+’ sign should line up with the red stripe. The ‘-‘ sign which is also denoted by a black stripe should match up with the blue line.
The module has 3 sets of power pins on the bottom for connecting to the breadboard power rails. If you install the module at the very end of the board, it will leave all breadboard tie-points available for prototyping.
Output Voltages
Slide switches on the module allow you to select either 5V or 3.3V for each of the 2 breadboard power rails. Moving them to the left applies 3.3VDC and moving them to the right applies 5VDC. There are also 2 small headers that provide another place to tap off 3.3V, 5V and GND if you need to.
Input Power
DC Power Jack:
Power can be input via a standard DC Power Jack. Input power should be kept between 7-10VDC when using the DC Power Jack.
USB Power:
The module also has a USB (Mini-B type) connector which you can use to power it off of if the other end is connected to a powered USB port such as on a computer or USB Hub. When this is used, the 5V from the USB is applied directly to the breadboard and also fed to the 3.3V regulator. The USB power has a poly fuse inline to provide some over-current protection to the USB port. Note: Do not connect both a DC power plug and powered USB at the same time or damage may result.
This USB port can also be used as an output to power a device like an Arduino board that requires 5VDC using a USB cable when the board is powered off the DC Jack. When hooking up a device to power it off of the USB connector, make sure that device is not already powered by a different source or damage may result.
Power Control:
Power is controlled from the source or by disconnecting the DC plug as there is no power button.
