You'll also need to make a common ground from the 5V power supply to the microcontroller\/Arduino. Since each LED can draw as much as 60mA (that's up to 3.5 Amps per panel if all LEDs are on bright white!) we suggest our 5V 2A power supply.

We also would like you to check out this breakout board for the TLC5947 PWM driver chip. This chip can control 24 separate channels of 12-bit PWM output.

Best of all, the design is completely chainable. As long as there's enough power for all the boards you can chain as many as you'd like, like a little trail of blue PCBs stretching out into the sunset. Each of the 24 output's is constant-current and open drain. You can drive multiple LEDs in series, with a V+ anode supply of up to 30V.

Trellis is an open-source backlight keypad driver system. It is easy to use, works with any 3mm LEDs and eight tiles can be tiled together on a shared I2C bus.\u003c\/p\u003e\n\u003cp\u003eThis PCB is specially made to match the Adafruit 4x4 elastomer keypad. Each Trellis PCB has 4x4 pads and 4x4 matching spots for 3mm LEDs. The circuitry on-board handles the background key presses and LED lighting for the 4x4 tile. However, it does not have any microcontroller or other 'brains' - an Arduino (or similar microcontroller) is required to control the Trellis to read the keypress data and let it know when to light up LEDs as desired.\u003c\/p\u003e\n\u003cp\u003eEach tile already has an I2C-controlled LED sequencer and keypad reader. The chip can control all 16 LEDs individually, turning them on or off. It cannot do grayscale or dimming. The same chip also reads any keypresses made with the rubber keypad. The connections are 'diode multiplexed' so you do not have to worry about \"ghosting\" when pressing multiple keys, each key is uniquely addressed.\u003c\/p\u003e\n\u003cp\u003eThe tiles have 3 address jumpers. You can tile up to 8 PCBs together (for a total of 4x32 or 16x8=128 buttons\/LEDs) on a single I2C bus, as long as each one has a unique address. All the tiles connect by the edges with solder and share the same power, ground, interrupt, and i2c clock\/data pins. So, you can easily set up to 128 LEDs and read up to 128 buttons using only 2 I2C wires! The tiles can be arranged in any configuration they want as long as each tile is connected to another with the 5 edge fingers.\u003c\/p\u003e\n\u003cp\u003eEach LED is multiplexed with a constant-current driver, so you can mix and match any colors you like. You don't need it to be all blue, all red, etc. Mix it up! Any 3mm LED can be used, although we find that diffused LEDs with 250mcd+ brightness look best.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eThis item is just for the Trellis driver PCB assembly: LEDs and buttons are not included\u003c\/strong\u003e.

Here at Adafruit, we feel your pain! After all, wouldn't it be awesome if you could control a matrix without tons of wiring? That's where these lovely LED matrix backpacks come in. We have them in three flavours - a mini 0.7\" 8x8, a mini 0.7\" 8 x 8 and a 4-digit 0.56\" 7-segment. They work perfectly with the matrices we stock in the Adafruit shop and make adding a bright little display trivial.\u003cbr\u003e\u003cbr\u003eThe matrices use a driver chip that does all the heavy lifting for you: They have a built-in clock so they multiplex the display. They use constant-current drivers for ultra-bright, consistent color, and 1\/16 step display dimming, all via a simple I2C interface. These 1.2\" matrix backpacks come with three address-selection jumpers so you can connect up to eight 1.2\" 8 x 8s together (or a combination, such as four 1.2\" 8 x 8s and four 7-segments, etc) on a single I2C bus.\u003cbr\u003e\u003cbr\u003eThe product kit comes with:\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eA fully tested and assembled 1.2\" LED backpack\u003c\/li\u003e\n\u003cli\u003e1.2\" 8x8 matrix square pixel yellow\u003c\/li\u003e\n\u003cli\u003e4-pin header\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003eA bit of soldering is required to attach the matrix onto the backpack but it's very easy to do and only takes about 5 minutes.\u003cbr\u003e\u003c\/p\u003e\n\u003cp\u003eOf course, in classic Adafruit fashion, we also have a detailed tutorial showing you how to solder, wire and control the display.

You cannot use this size panel with an Arduino UNO (ATmega328) or ATmega32u4 - you need a chip with more RAM! These displays are technically 'chainable' - connect one output to the next input - as long as you have the RAM and CPU to handle it\u003c\/p\u003e\n\u003cp\u003eThis display does best with a high speed, high RAM microcontroller like a SAMD21, SAMD51, ESP32, etc. 8-bit micros are going to struggle if they work at all. The good news is that the display is pre-white balanced with nice uniformity so if you turn on all the LEDs it's not a particularly tinted white.\u003c\/p\u003e\n\u003ch3\u003ePower Requirements\u003c\/h3\u003e\n\u003cp\u003eThere's a lot of LEDs!

You may have to use consecutive or special pins depending on the driver firmware. We'll be honest: folks who try to wire directly are usually not successful, its easy to get confused and misconnect.
