VEX Speaker
 Got a new VEX Speaker?


VEX Robotics just announced (and released) their new Speaker accessory for the VEX Cortex Microcontroller. This cool new speaker will allow you to play tones, sounds and wave (.wav) sound files from your VEX Cortex. The new speaker plugs into the “SP” port on the Cortex – check near the bottom of the sensor bank of ports. The speaker even has a built in volume control:


Check out our cool unboxing photos below, exclusive from the VEX World Championships!


The awesome thing with this new speaker accessory is that ROBOTC already has support for this new speaker built into version 3.08! For more information on how to use the speaker, check the ROBOTC help documentation built into ROBOTC, or look at our new (under construction) ROBOTC code wiki!
