# RGB Matrix Bonnet
|
||
|
|
|
||
|
|
This HAT plugs into your Pi and makes it super easy to control RGB matrices, such as those you see in the likes of Times square, enabling you to create a colourful scrolling display or mini LED wall.
|
||
|
|
|
||
|
|
* A 5V power supply is also required for powering the matrix itself.
|
||
|
|
* To calculate the max current of your matrix set up, multiply the width of all the chained matrix by 0.12 : A 32 pixel wide matrix needs 32*0.12 = 3.85A so pick up a 5V 4A power supply.
|
||
|
|
* This HAT is only for use with HUB75 type RGB Matrices. Not for use with NeoPixel, DotStar, or other 'addressable' LEDs.
|
||
|
|
|
||
|
|
Features:
|
||
|
|
|
||
|
|
* Simple design - plug in power, plug in IDC cable, code.
|
||
|
|
* Power protection circuitry - you can plug a 5V 4A wall adapter into the HAT and it will automatically protect against negative, over or under-voltages.
|
||
|
|
* On-board level shifters - these convert the Raspberry Pi's 3.3V to 5.0V logic for clean and glitch free matrix driving
|
||
|
|
|
||
|
|
This bonnet is compatible with any Pi that has a 2x20 header.
