I get an unregulated connection to my raw power supply, but it isn't tied to the 'On/Off' switch. I know I could use a simple Voltage regulator to manage this myself, but having a switched passthrough of the unregulated power supply for other uses would be very convenient.Īs an aside, I did notice that I could kinda get what I wanted by wiring the '+' and '-' connections which were intended as a supply input out to my board. I have a 12V, 2.0A power supply that I would like to have power an LED light strip, but use this board to deliver the stepped down Voltage for a microcontroller. Ideal for CCTV UK mains plug Lead length: 3.6m 2. DHT11 Humitidy and Temperature Sensor.fzpz DHT22 Humidity and Temperature Sensor.fzpz DS18B20 1-Wire Temperature Sensor. It features a UK mains plug and 2.1mm DC output plug with a 3.6m lead length. A 12V, 2A switch mode power supply unit that is ideal for use with CCTV. in addition to the necessary external power supply, which may be 9V or 12V. This buck-boost converter chip can handle a wide range of voltages (3-12V) and has some really nice extras such as power good output, 2A internal switch, synchronous conversion, excellent efficiency, and 2.

One suggestion I would have that would make this product even more useful would be to somehow add a way to have a passthrough of the power supply's original voltage to the board. 12V, 2A, In Line CCTV Power Supply, 2.1mm Plug. Draw in Fritzing an integrated L298N, two linear potentiometers of 10K and.

I like the fact that you can easily switch between different voltages, and you have a nice convenient power switch on the board. This is a very useful product to more easily get power to your breadboards from a variety of power bricks. As shown in Figure 1, there are three power supply in which two are of the same specification and one more is from the 12V 1A direct current power supply.
