 Qwiic cables are a popular choice for connecting various sensors and actuators to microcontrollers and other devices. They feature a 4-wire JST-SH connector on each end. One unique aspect of Qwiic cables is their asymmetrical orientation. One connector will typically be `top-facing` while the other is `bottom-facing.` This deliberate design choice helps with cable routing and prevents accidental misconnections, making it easier to create clean and organized setups.
