Suitable development environments and frameworks include:

• ESP-IDF

• Arduino framework

• PlatformIO

• C/C++ embedded development

• Wi-Fi application development

• Bluetooth LE application development

• USB application development

The module is intended for integration into a custom hardware design rather than being a complete development board. A custom PCB should provide the required power regulation, USB circuitry where needed, reset/boot circuitry, antenna clearance, decoupling, and exposed GPIO connections according to Espressif's hardware design recommendations.

PCB Design Considerations:

• Use the official ESP32-S3-WROOM-1 datasheet and hardware design documentation when designing a custom PCB.

• Provide a stable and suitable power supply.

• Place appropriate decoupling capacitors close to power pins.

• Follow Espressif's recommended PCB layout around the integrated PCB antenna.

• Keep copper, ground planes, traces, and other components away from the antenna clearance area as specified by Espressif.

• Provide appropriate boot and reset circuitry where required.

• Consider USB routing requirements when using USB functionality.

• Verify GPIO availability because not every ESP32-S3 peripheral signal is necessarily exposed through every module pin. (Espressif Systems)
