Review on Glarks 1940Pcs 2.5mm Pitch Male/Female Plug Housing and Pin Header Assortment Kit | Perfect Compatibility with JST-SM Connector | 2/3/4/5/6/7/8/9 Pin Male and Female Options Available by Jasmine Smith

I'm experimenting with Arduino IoT implementations and need a way to connect external devices to PCBs. This set is perfect for that purpose. I did a rough inventory and there is an equal number of plugs and sockets and a fair amount of each. Good quality. A NOTICE. Do not purchase the recommended crimping tool (Iwiss SN-28B) for these connectors. The matrices are too wide. Instead, purchase an Iwiss SN-01BM crimping tool with the narrow jaws required for these crimp connectors. With the right tool, the wire and insulation are stretched taut. SN-01BM works with 28 to 20 gauge wire.
