I have a few different types of DC-DC voltage converters in my kit. USB 5V DC Boost Step-up Power Supply Module DC-DC 0.9V-5V.XL6009 DC-DC Converter Constant Voltage Step Up Down with Automatic Buck-Boost.Adjustable 4V-12V Step-Up Voltage Regulator U3V50ALV.Mini-360 DC-DC Buck Converter Step Down Module 4.75V-23V to 1V-17V.As long as all the batteries have the same capacity, for a pack of batteries, charging can be made using a bench top power supply.ĭC – DC Voltage Converters Various DC-DC Voltage Converter modules. Battery holders such as the 10 x AA holder shown above is an economical way to power projects using standard rechargeable batteries.Another portable power option is a Li-ion 18650 battery with Lithium Battery Charging Protection Module – TP4056.Ideal for powering projects from a USB power bank. A super short USB lead connected to a micro USB breakout to jumper connector.Use a USB adaptor to add a DC-DC converter for a wider voltage supply range. Power banks are useful for portable projects that have a constant current draw.Put a jumper connector on the back and it is ready to go for outdoor projects. 6-volt solar panel module measuring 136 x 110mm.Power Source Modules Various Power Source Modules. However, the point of these examples is to demonstrate the usefulness of adding jumper wires to modules. The collection of modules I have were created over a long period of time as and when I needed them. Therefore other module types will be covered in later articles.īelow you will find examples of modules to help drive some inspiration. This is just to avoid the article getting too long. The electronic modules featured in this article are the type that can function without a micro-controller or Arduino compatible. You can also cut to length to have bare wires at one end for soldering to modules. You can peel off a smaller ribbon as required. Jumper wires, in the picture above, are typical of what you can buy. However, the single pin housings might be replaceable with multiple pin terminal housings. Incidentally, though, these jumper wires will be supplied in single pin housings. This is because readily made jumper wires are commonly available from websites such as Ebay and Amazon. In case you do not have an SN-28B crimping tool you can still apply connectors to modules in similar ways. If You Can’t Make Your Own Jumper Wires Single pin jumper wires in a flat 40 wire ribbon cable. Of course, a short male to male or female to female jumper wires can be made to convert the connection type. Using a convention like this will avoid accidental shorting of unconnected connectors. For instance, if the connector is supplying power or is an output type I use a female type connector. I have a sort of convention when choosing either male or female connection type. Jumper Wires Connection Convention DC-DC Adjustable Step-up Boost Power Converter Module XL6009 with jumper wires attached. Thus making a more compact circuit and saving a breadboard – on a long-term project especially. So using the SN-28B terminal crimping tool to make connectors, we can join the different electronic modules together without needing to breadboard. Hence now you can compare light levels between each room in your house. Yet connecting the voltmeter module to a small solar panel module, you create a useful function. For instance, a voltmeter module by itself cannot perform a useful function. However, the modules by themselves might not provide any useful function unless connected to another module. These electronic modules are generally self-contained circuits that perform a specific function. But rather than leave it there, I’m going to show some electronic modules in my kit where I’ve added connectors. In the last article, I introduce the SN-28B Terminal crimping tool to make jumper wires or terminal connectors.
