Adafruit Matrix Portal - CircuitPython Powered Internet Display
We have ✅ 5 available of the AF-4745 in our Sydney warehouse. An extra 100 units available with a short lead time.
The Adafruit Matrix Portal is a plug-and-play controller for HUB-75 RGB LED matrix panels. Powered by an ATSAMD51 (Cortex M4) with an ESP32 WiFi coprocessor, it plugs directly into the back of any compatible matrix — no soldering or wiring required. Just attach power and start coding in CircuitPython or Arduino.
The dual-processor design lets the SAMD51 handle high-speed RGB matrix updates and native USB, while the ESP32 manages WiFi with TLS/SSL encryption. This makes it ideal for internet-connected LED displays showing live data, animations, and interactive content.
