• LED brightness control by holding the A key
• Added possibility to add any color or brightness (within code)
• Separate key A and Joystick Center key codes (in original code they were the same)
• DMD2 mode color changed to blue (looks cooler)
• Button special function changes (will be described later)
• Added reset option by holding A,B,C keys. This is a workaround for the issue when Bluetooth auto-pairing did not work anymore, e.g., when the moto buttons are powered on, auto-connection to the phone/tablet does not work

• Some old USB-A cable for power and other wires
• Seeed Studio XIAO nRF52840 series (I used Seeed Studio XIAO nRF52840 Sense)
• 3x waterproof buttons (I used V12B-10N-A)
• 5-way joystick (I used JS5208)
• RGB LED common anode ONLY (I used OSTAMA5B31A) Do not use common cathode, I already burned 2x Seeed boards to realize that
• 3D printed case with some screws (the case is waterproof enough to hold rain and some submersion. I've already been using it for 1 year, no issues. But use some super glue on the TPU gasket and glue gun around holes from inside). All TPU and PETG (or alternative filament) STLs are in 3D folder.
