Frequently Asked Questions

How do I upload my first Arduino sketch to the ESP32-WROVER-B board?

First, install the ESP32 board support via the Arduino IDE Board Manager. Connect the board via Micro-USB, select 'ESP32 Wrover Module' as the target, choose the correct COM port, and press upload. Hold the BOOT button if the sketch fails to upload initially to force the board into download mode. The onboard LED will indicate successful programming.

What is the advantage of the 4MB PSRAM on the ESP32-WROVER-B?

The 4MB PSRAM provides additional volatile memory for storing large data buffers, which is essential for applications like camera image processing, audio streaming, or complex data structures in machine learning. It allows the ESP32 to handle tasks that exceed the limited internal RAM, enabling more advanced projects without external memory chips.

How do I control the onboard RGB LED (WS2812) using Arduino code?

The RGB LED is an addressable WS2812 LED connected to GPIO18. Use the FastLED or NeoPixel library. Include the library, define the data pin as 18 and number of LEDs as 1, then use setPixelColor() and show() functions to set colors. Ensure your power supply is adequate, as the LED can draw significant current at full brightness.
