Here is a tiny 4-pin Qwiic 1mm JST connector. This connector is used on all our Qwiic based boards and can be used to create your own I2C based device compatible with the Qwiic system. Additionally, this connector will mate with all of our Qwiic cables with a solid lock. The SparkFun Qwiic connect system is an ecosystem of I2C sensors, actuators, shields, and cables that make prototyping faster and less prone to error. All Qwiic enabled boards use a common 1mm pitch, 4-pin JST connector. This reduces the amount of required PCB space, and polarized connections mean you can’t hook it up wrong.
