## Description

Make an internet-connected RGB matrix display without the usual wiring fuss. This board plugs straight into the back of a compatible HUB75 RGB matrix, giving you an easy way to build colourful signs, clocks, status panels and data dashboards with CircuitPython or Arduino.This version uses a u.FL antenna connector, so an external antenna is required for WiFi and Bluetooth operation. That makes it handy when you want the antenna positioned outside an enclosure, but please note that the u.FL antenna and any adapter are not included.It is designed to work with Adafruit HUB75 displays from 16x32 up to 64x64, or you can use standard 2x8 IDC cables to connect from the front instead. The included screws let you attach the power cable to the power terminals with a regular screwdriver, and the board is powered over USB Type-C. For larger builds, you can chain multiple displays or panelise them into a bigger grid, with a separate 5V supply recommended for the matrices.On the software side, the ESP32-S3 is supported in both Arduino and CircuitPython, and Adafruit's Protomatter library handles matrix driving on the chipset while the board takes care of the wiring and level shifting. It comes fully assembled and preprogrammed with a basic demo for 32x64 LED matrices.Features:Processor: ESP32-S3 processor, 8 MB flash, 2 MB of SRAM, with full Arduino or CircuitPython support.Wireless: WiFi and Bluetooth® LE baked right in, full Arduino support.CircuitPython wireless support: CircuitPython only supports WiFi at this time, not BLE on the S3 chip.USB: USB Type C connector for data and power connectivity.STEMMA QT: I2C STEMMA QT connector for plug-n-play use of any of our STEMMA QT devices or sensors.Grove compatibility: Can also be used with any Grove I2C devices using this adapter cable.JST connector: JST 3-pin connector that also has analog input for quick connection with any JST PH 2.0mm pitch cable.Accelerometer: LIS3DH accelerometer for digital sand projects or detecting taps/orientation.GPIO breakout strip: Has reset, boot selection, TX debug output, and 6 GPIO including 4 analog inputs with PWM, SPI, or I2S support for adding other hardware.Address E line jumper: Address E line jumper for use with 64x64 matrices.Address E default: Check your matrix to see which pin is used for address E, we default to pin 8.Buttons: Two user interface buttons + one reset button.Status LEDs: Indicator NeoPixel and red LED.Power LEDs: Green power indicator LEDs for both 3V and 5V power.HUB75 socket: 2x10 socket connector fits snugly into 2x8 HUB75 ports without worrying about 'off by one' errors.IDC connector: 2x8 IDC plug connector works with standard cables that come with matrices.Parallel output drive: The S3 has a parallel output drive peripheral, which means that controlling the matrix is done without bitbanging.Dual-core operation: The S3 has two cores, so one can be dedicated to WiFi networking or matrix control while the other runs your code.Native USB: With native USB, it's easy to have it act like a keyboard, or mouse, or MIDI device, and it also has plenty of I2C, SPI, I2S, UART, and analog inputs.Flash memory: Lots of memory: 8MB of Flash means plenty of space for code, files, GIFs and more.PSRAM: 2MB of PSRAM means you can read and parse a lot of IoT data and still have plenty of RAM for the matrix display buffers.Audio note: The only real thing missing from the original Matrix Portal is the S3 does not have an analog output DAC pin.Audio recommendation: We recommend an I2S amplifier for audio instead.Included: Comes with one fully programmed and assembled MatrixPortal, preprogrammed with a basic display demo for 32x64 LED matrices.RGB matrix not included: Does not come with an RGB Matrix.Power supply not included: Does not come with a USB Type-C power supply.Antenna note: Please note: this version does not come with an onboard antenna.External antenna required: You will need a uFL connector antenna, such as 2.4GHz Mini Flexible WiFi Antenna - not included.A good fit for connected displays, IoT dashboards and interactive matrix projects where you want fast setup, built-in wireless and easy expansion with STEMMA QT or other GPIO peripherals.

**Product Type:** LED Matrix Controller
