The SparkFun Extended Qwiic Shield for Teensy provides you with a quick and easy way to enter into SparkFun\'s Qwiic ecosystem with your Teensy boards. This shield is sized to work with the footprint of Teensy 4.1, Teensy 3.6, and Teensy 3.5. This shield connects the I2C bus (GND, 3.3V, SDA, and SCL) on your Teensy to four SparkFun Qwiic connectors (two horizontally and two vertically mounted). The Qwiic ecosystem allows for easy daisy chaining so, as long as your devices are on different addresses, you can connect as many Qwiic devices as you\'d like.
We have also added a \"PROG\" button on this shield that is electrically parallel with the \"PROG\" button on the Teensy Boards so you can choose to use either the button on your Teensy or the button on the shield to put your Teensy into Programming mode.
The Qwiic Shield for Teensy comes with two 24-pin and one 5-pin headers and will need to solder the headers to the shield and, if necessary, to your Teensy board. Take care to match the markings on the Qwiic Shield to the appropriate pins on your Teensy to avoid possibly damaging your boards.
*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 canâ€™t hook it up wrong.*
