Joy-Con IR Camera Module. Also residing in the right Joy-Con is another feature, the motion IR camera. This camera is an infrared CMOS image sensor that is used to detect object shape and distance and, according to Ars Technica and Nintendo, will be able to record full video in the future. This camera sensor appears likely to be manufactured. This video shows you how to unload the blade and insert a pen into the machine for drawing. If playback doesn't begin shortly, try restarting your device. Videos you watch may be added to the TV's watch history and influence TV recommendations. To avoid this, cancel and sign in to YouTube on your computer. Input Display by MoonsPod.

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.
| Controller | 1.0.0 |
|---|---|
| Joy-Con Left (Blue) | flash dump |
| Joy-Con Right (Red) | flash dump |
The flash is in a patch-ram format. Tools for dealing with it are available [3].A dump of the ROM region (taken while firmware was running) can be found here. Note this is the same SoC used on the other controller models, as well.

Left & Right Separate Joy-con
When paired directly to a computer over bluetooth, the joy-con both provide identical HID input report descriptor. This does not appear to include motion controls, IR data, or NFC. They both behave as detached single-player controllers.

Colors
HEX codes for the colors shown in the 'Controllers' menu of the Switch UI can be found in a Joy-con SPI dump starting at offset 0x6050. Body color is first followed by button color and each is 3 bytes long. These values are able to be re-written with any HEX color value to make the Joy-cons show up as different colors in the UI. The following is a list of official HEX colors recovered from SPI dumps.
