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.
Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, TinyGO, or even use the Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for CircuitPython, MakeCode, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
