WS2812 - Neopixel LED Strip PH 2A Connector
Posted: Mon Oct 25, 2021 11:54 am
I love the JST PH connector. It's very versatile and compact. You can get it in surface mount SMD, or Through Hole package. It's rated for 100V, 2A. If you need more current, then there is the JST XH connector. It's rated for 250V, 3A. There are even higher rated connectors, but I haven't had a need to use them yet.
I was chatting with a friend last night and he was showing me a RGB LED lamp he was building out of folded origami opaque plastic sheet. It reminded me that I was going to have a go at deigning some small 26mm long connector boards that have a PH connector at one end, and exposed solderable traces at the other end. This will allow you to solder down either 8mm to 12mm wide WS2812 RGB LED strips. There are notches in the PCB to help hold heatshrink in place to help hold the LED strip to the board and to act as a bit of a strain release. Two layers of heatshrink should do the trick - kind of what I have used below: The board will also work with the higher density 12mm wide LED strips, and the PH connector could be swapped out for a XH connector. It will just fit - kind of: The board includes provision of a power indicator LED and can be soldered on if required, and a solder jumper to enable it: It cost under A$14 (inc. shipping) for five panels of 18 PCB's for a toal of 90 PCBs. Thanks you JLCPCB!
