Printed Circuit Boards
Low-Noise Design
The routing is optimized for low noise and efficient power flow between the solar input, charge controller, battery, and ESP32. Solid ground planes improve EMI performance, which is critical for wireless operation. High-current charging paths are isolated from sensitive control and LED signal lines. This design ensures stable LED control, reliable piezo operation, and long-term performance in outdoor environments
The PCB is cleanly organized with the ESP32 module at the center to ensure stable power distribution and good RF performance. Dedicated sections handle solar charging, battery management, and LED driving, improving reliability and ease of debugging. Clearly labeled pads and connectors simplify assembly and testing. The layout supports low-power operation, making it suitable for solar-powered garden indicators that run continuously with minimal maintenance.
This is a compact, circular ESP32-based status indicator board designed for outdoor garden use. The ESP32 acts as the main controller for status LEDs and system logic, while the solar panel input and onboard charge controller enable autonomous operation using a rechargeable battery. Status LEDs are placed around the perimeter for clear 360-degree visibility, and a piezo buzzer provides audible alerts for notifications or warnings. The form factor is optimized for enclosure mounting and outdoor aesthetics.
Custom-designed plug-and-play control board with extensive GPIO breakout for quick and reliable sensor integration. Features organized header pinouts, onboard signal conditioning, and stackable form factor compatible with standard development boards for rapid prototyping and deployment.
