When 0.1″ is too big, and JST PH’s too chunky, the ultra-slim “PicoBlade” is a reliable alternative. These are only 1.25mm pitch, but have a nice clicky connection.
This cable is nice and long, 200mm in fact. It’s got both small form factor (won’t take up a lot of real estate on your PCB) and friction lock to make easy-breezy connections to your HalloWing or anything else with a 1.25mm PicoBlade connection.
Make a robot friend with Adafruit’s CRICKIT – A Creative Robotics & Interactive Construction Kit. It’s an add-on to our popular Circuit Playground Express, FEATHER and other platforms to make and program robots with CircuitPython, MakeCode, and Arduino. Start controlling motors, servos, solenoids. You also get signal pins, capacitive touch sensors, a NeoPixel driver and amplified speaker output. It complements & extends your boards so you can still use all the goodies on the microcontroller, now you have a robotics playground as well.
