Qwiic JST Connector - SMD 4-Pin (Vertical)

Here is a tiny 4-pin, 1mm pitch Qwiic (or JST) connector. This connector mounts to allow you to connect your cable vertically, great for tight spaces. This connector is used on all of 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.

Need a custom board? This component can be found in SparkFun's À La Carte board builder. You can have a custom design fabricated with this component - and your choice of hundreds of other sensors, actuators and wireless devices - delivered to you in just a few weeks.

    I found out the hard way that although it is possible (though difficult) to solder a vertical JST connector onto a footprint for a horizontal connector, the pins will be reversed (that is to say, GND will be where SCL should be, 3.3V where SDA should be, SDA will be where 3.3V should be, and SCL will be where GND should be).

    I'm posting this as a cautionary tale for others!
