Universal Zigbee Sensor Board (ESP32-H2-Supermini)

Introduction

This repository contains the KiCad 9.0 project files for a universal Zigbee sensor board based on the ESP32-H2-Supermini module. This board is designed to be flexible and adaptable for various sensor applications, providing a compact and low-power solution for Zigbee-based IoT projects.

Features

• ESP32-H2-Supermini: Utilizes the Espressif ESP32-H2-Supermini module, offering robust Zigbee connectivity and low power consumption.
• Universal Sensor Interface: Designed with multiple GPIO pins exposed for easy connection of various sensors (e.g., temperature, humidity, light, motion).
• Power Supply Flexibility: Supports various power supply options (e.g., battery, external power).
• Compact Design: Designed to be small and easily integrated into different enclosures.
• KiCad 9.0 Project: Fully documented project in KiCad 9.0 for easy modification and customization.

Getting Started

Prerequisites

• KiCad 9.0 or later installed.
• ESP32-H2-Supermini datasheet and documentation.
• Required sensor datasheets.
• A computer running a compatible operating system (Windows, macOS, Linux).

Setup

1. Clone the Repository:

   git clone https://github.com/manupawickramasinghe/universal-zigbee-sensor-kicad.git
   cd universal-zigbee-sensor-kicad

2. Open the Project in KiCad:
   • Launch KiCad 9.0.
   • Click "File" -> "Open Project...".
   • Navigate to the cloned repository folder and select the .kicad_pro file.
3. Explore the Project:
   • Schematic Editor: Open the schematic editor to view the circuit diagram. Examine the ESP32-H2-Supermini connections, sensor interfaces, and power supply circuitry.
   • PCB Layout Editor: Open the PCB layout editor to view the board layout. Inspect the component placement, routing, and board dimensions.
   • Symbol and Footprint Libraries: Ensure that the necessary symbol and footprint libraries are installed. The project should contain the needed libraries. However if you are missing any, they will need to be added.
4. Review the Datasheets:
   • Refer to the ESP32-H2-Supermini datasheet to understand the pin functions and specifications.
   • Review the datasheets for the sensors you plan to use to ensure compatibility and proper connection.
5. Customize the Design (Optional):
   • Modify the schematic and PCB layout to suit your specific sensor application.
   • Add or remove components as needed.
   • Adjust the routing and component placement for optimal performance.
6. Generate Gerber Files:
   • Once you are satisfied with the design, generate Gerber files for PCB manufacturing.
   • In the PCB layout editor, click "File" -> "Fabrication Outputs" -> "Gerber Files...".
   • Configure the Gerber settings and generate the files.
7. Order PCBs:
   • Use the generated Gerber files to order PCBs from a PCB manufacturer.
8. Assemble the Board:
   • Solder the components onto the PCB.
   • Ensure proper orientation and soldering quality.
9. Programming the ESP32-H2-Supermini:
   • Refer to the Espressif documentation for programming the ESP32-H2.
   • You will need a compatible development environment (e.g., ESP-IDF).
   • Develop and upload your firmware to the ESP32-H2-Supermini to control the sensors and manage Zigbee communication.
10. Testing:
    • Connect your sensors to the board.
    • Power up the board and test the functionality of the sensors and Zigbee communication.
