Know before you buy
No, the Matrix Portal S3 is designed for a solder-free experience. It plugs directly into the back of compatible HUB-75 LED matrices, or you can connect it via an IDC cable if you prefer a front-facing setup.
The Matrix Portal S3 supports HUB-75 compatible RGB matrices ranging from 16x32 up to 64x64 pixels. It is optimized for these standard sizes to ensure stable performance.
While the USB-C port powers the board itself, it may not provide enough current for larger or brighter LED matrices. For setups larger than a single small panel, we recommend using a dedicated 5V external power supply to prevent flickering or power-related resets.
While the Matrix Portal S3 is primarily designed for CircuitPython, the ESP32-S3 processor is also compatible with the Arduino IDE. However, using CircuitPython is recommended for the easiest experience when setting up internet-connected displays.
Yes, the board supports chaining multiple HUB-75 panels. Keep in mind that as you increase the total number of pixels, you will need to ensure your power supply can handle the increased current draw.
Yes, the integrated ESP32-S3 processor provides both Wi-Fi and Bluetooth capabilities. This allows you to easily fetch real-time data from the internet, such as weather updates or social media feeds, to display on your matrix.
