You can see that the inner crimp grabs all of the wires and the outer crimp grabs the insulation on the wire. Here is a picture of what we are trying to achieve with the crimp. The set that is near the strip is for the insulation. The set in the middle crimps the raw wire. In the picture below you can see that there are two sets of wings. Here is a zoom of some of the connectors where you can see the wings. One set holds the wire and the other holds the insulation. When you buy the crimp connectors, they will come on a metal strips which are meant to go through a machine that automatically crimps wires in China (obviously we are going to do it manually).Įach crimp connector has two sets of wings, which you will bend during the process.

Before I tell you HOW to do a good crimp, I want to show you what you are trying to do. So… you really want to make your own crimps? OK. Here is a pile of the the raw wires with crimps on one end:Īnd here are some that are pre-made into 6-pin connections. It is possible that purchase pre-crimped wires which will then easily slip inside of the connector housing to create almost any combination you might want. The first thing that I will say about the crimping process is that you should consider not doing it. I will write about these other two types later on. I will also observe that the “JST” problem extends to some other crimp connectors including “Molex” and “Dupont” (which has a crazy history). The crimps are a bit hard to make and there is this inherent assumption everywhere that you should have just “known” how to do this.
Honestly the whole thing is pretty annoying. Take you through my crimping procedure – which seems to work.Tour the common version of the JST connectors, where they are used.Finally, you will discover that there are a boatload of crimping tools that range in price from $10 (for a crap pair of pliers) to $500 (for the OEM JST Crimpers) Then you will discover that there are tons of youtube videos that “show” you how to crimp JST connectors, and that most of them are absolute crap, particularly if you are 50 years old can barely see the freaking crimp connectors. The next thing that you will discover is that all around the internet on the maker websites you will find people referring to connections as “JST” and acting like there is only one type of JST connector. The first thing that you will discover is that “JST” stands for Japan Solderless Technology and that they make about 50,000 different types of connectors. In order to do this I needed to connect to the “ 6-pin JST connector for direct connection” which is on the right side of the board in the picture below.īut, what I might ask, is a JST Connector? And, how might you make a connection to it. Specifically, I was using the PMOD HB5 as a solid state switch to drive a higher voltage, higher current than the GPIO on the PSoC 6 can drive.
Last week I was using a CY8CKIT-062-BLE PSoC 6 development kit with a Digilent PMOD-HB5 connected to the PMOD port. The Wikipedia article on JST has a nice table.
