Frequently Asked Questions

Which ESP32 modules are compatible with this expansion board?

This board is designed for modules following the ESP32-DevKitC-32 footprint, including the ESP-WROOM-32, ESP-WROOM-32D, ESP-WROOM-32U, and various WROVER modules. Ensure your module's pinout matches the 38-pin layout. You typically solder or socket the module onto the board's central pads.

How do I power and program the ESP32 using this expansion board?

Connect a USB Type-C cable from your computer or a 5V power adapter to the board's Type-C port. This provides both power and a serial COM port for flashing firmware via the Arduino IDE, ESP-IDF, or other tools. The onboard circuitry manages the voltage regulation for the ESP32 module.

Can I use all 38 GPIO pins simultaneously with this board?

Yes, all 38 broken-out pins are accessible. However, consider ESP32 pin multiplexing and restrictions: some pins are used for internal flash, strapping, or have pull-up requirements. Always consult your module's datasheet to avoid conflicts, especially with GPIOs 6-11 which are connected to internal SPI flash.
