Product Description
This expansion board features a dual-interface design, allowing you to power your project via USB Type-C, Micro-USB, or a standard DC Barrel Jack. This flexibility is essential for high-power IoT projects where a computer's USB port might not provide enough current for multiple sensors or relays. The board also includes a Power-On LED indicator and a manual reset button, making it a complete workstation for ESP32 development.
Key Features
No-Solder Prototyping: The pre-soldered headers allow you to drop in your ESP32 module and start connecting peripherals instantly.
Flexible Power Logic: A built-in jumper allows you to switch the VCC rail between 3.3V and 5V, making it compatible with both low-power sensors and 5V modules like ultrasonic sensors.
Triple Power Input: Supports a wide range of power sources, from a phone charger (USB-C) to a 12V wall adapter (DC Jack).
Stable Signal Transmission: The double-layer PCB design ensures clean signals and high reliability for SPI, I2C, and UART communications.
