fmt2rgb888(fb->buf, fb->len, fb->format, image_matrix->item); 4- print the text of your choice over that matrix (FF is red color, you can use any uint32_t. Also, take a look at the rgb_print function posted in @sashok1337 response; you can modify it to send the position of the string): rgb_print(image_matrix, 0x000000FF, "test");

It also has DACs, ADC, PWM, and tons of GPIO, so it can handle the high speed updating of the RGB matrix. Meanwhile, the ESP32 has secure WiFi capabilities, and plenty of Flash and RAM to buffer sockets. By letting the ESP32 focus on the complex TLS/SSL computation and socket buffering, it frees up the SAMD51 to act as the user interface.

In the case of the RGB LED, the schematic shows three resistors (R149, R150 and R151) connected to ground. That's not what's on the board! Instead, the three LED anodes are connected together to +3.3V and then each resistor in series with the LED is connected to the drain of a small mosfet (Q6, Q7 and Q8).
