Adafruit Matrix Portal S3 CircuitPython Powered Internet Display

With the Adafruit Matrix Portal add-on for RGB matrices, creating high-performance, internet-connected LED displays has never been easier - no soldering, no wiring, just plug and play. 

Plug the socket directly into the back of any HUB-75 compatible display (any of the ones we have in stock will work). Use the included screws to attach the power cable to the power connectors with a regular screwdriver, then power it with any USB-C power adapter. (For larger projects you can power the matrices with a separate 5V power supply).

Then program your project in CircuitPython or Arduino. Our Protomatter Matrix library works great on the ESP32-S3 chipset.

Here's what you get:

  • ESP32-S3 processor, 8MB Flash , 2MB SRAM, with full Arduino or CircuitPython support

  • WiFi and Bluetooth LE integrated, full Arduino support. CircuitPython currently only supports WiFi, not BLE on the S3 chip.

  • USB Type-C port for data and power connection

  • I2C STEMMA QT connector for plug-n-play use with any of our STEMMA QT devices or sensors, can also be used with Allen Grove I2C devices with this adapter cable

  • JST 3-pin connector that also has an analog input for quick connection to any JST PH 2.0mm pitch cable.

  • LIS3DH accelerometer for digital sand projects or for typing/orientation detection.

  • GPIO breakout bar - has reset, boot select, TX debug output and 6 GPIO including 4 analog inputs with PWM, SPI or I2S support for adding other hardware.

  • Address E line jumper for use with 64x64 matrices (check your matrix to see which pin is used for Address E, we default to pin 8

  • Two user interface buttons + one reset button

  • Display NeoPixel and red LED

  • Green power indicator LEDs for 3V and 5V power

  • 2x10 socket connector fits perfectly into 2x8 HUB75 ports without worrying about 'off-one-off' errors

  • 2x8 IDC connector works with standard cables that come with matrices.

The Matrix Portal uses an Espressif ESP32-S3 Wi-Fi+BLE chipset and omitted the SAMD51 from the original Matrix Portal due to chip shortages. But it turns out that the S3 is great all on its own at doing all the work of the original:

  • The S3 has a parallel output driver peripheral, meaning control of the matrix is ​​done without bitbanging.

  • The S3 has two cores, so one can be used for WiFi networking or matrix control and the other for your code.

  • With native USB, it's easy to make it act like a keyboard, mouse or MIDI device, and it also has plenty of I2C, SPI, I2S, UART and analog inputs.

  • Lots of storage: 8MB Flash means plenty of space for code, files, GIFs and more. 2MB PSRAM means you can read and analyze lots of IoT data and still have plenty of RAM for the matrix display buffers.

The only thing really missing from the original Matrix Portal is that the S3 doesn't have an analog output DAC pin. We recommend an I2S amplifier for audio instead.
Comes with a fully programmed and assembled Matrix Portal, pre-programmed with a demo for 32x64 LED matrices.

Does not come with an RGB matrix (used any HUB75 compatible matrix) or a USB Type-C power supply.
