Adafruit MakeCode Sync Cable, micro B USB to micro B USB, 1 meter long, 4342

Ready Players 1 and 2? Double up on your MakeCode gaming with a Sync Cable! We got this Micro B USB to Micro B USB cable specially made to connect you and your frenemy for co-op fun or player-versus-player showdowns. Works with our PyBadges and PyGamer - we connected the JACDAC pin to the 'extra' ID pin of the Micro B cable so data can pass back and forth.

It's one meter long, so you and your cohort will have enough elbow room to button-mash without feeling too tethered to each other.

To test your cable, you can load this UF2 onto your PyGamer/PyBadge and connect together with this cable.

You can also use this cable for some USB-OTG uses, as long as your USB host is OK with the ID pin floating.
