==Joy-Con ~~Connector Pinout==~~

==Firmware==

''See also: [[Joy-Con Firmware]]''

The firmware of the Joy-Cons seems to be generic across all instances. Details such as the handedness of the controller and the color is just indicated in a configuration part of the flash. Judging by quick glance at the firmware, it's probably identical to that used on the Pro Controller as well.

The flash is in a patch-ram format. Tools for dealing with it are available [https://github.com/shuffle2/nxpad].

~~When first connected~~ the ~~baud rate is at 1000000bps~~(!)~~, after the initial handshake the speed~~ is ~~then switched to 3125000bps(!!). The handshake probably exchanges information about~~ the ~~side of the Joy-Con,~~ the ~~color~~, ~~and Bluetooth address etc~~.

A dump of the ROM region (taken while firmware was running) can be found [[:File:bcm20734_rom.bin|here]]. Note this is the same SoC used on the other controller models, as well.
