Pin Reference

The Beetle ESP32-C6 provides access to various GPIO pins. Refer to the board’s pinout diagram for specific pin assignments.

Common Pin Mappings

• I2C: GPI19 (SDA), GPI20 (SCL)
• SPI: GPIO22 (MOSI), GPIO21 (MISO), GPIO23 (SCK)

Power Considerations

The Beetle ESP32-C6 can be powered via:

• USB-C: 5V power supply
• Battery: Connect to battery pins (check polarity)
• 3.3V Pin: Direct 3.3V regulated power

Notes

• The ESP32-C6 uses a RISC-V architecture (not Xtensa like older ESP32 models)
• ESP-IDF framework is recommended for ESP32-C6 support
• WiFi 6 features provide improved performance and efficiency
• Lower power consumption compared to older ESP32 variants
