esp32-h2-supermini-kicad

This project focuses on the comprehensive development of a KiCad library component for the ESP32-H2-Supermini module. The goal is to provide accurate and high-quality resources for designers using KiCad to integrate this powerful wireless microcontroller into their projects.

ESP32-H2 Supermini Description

The ESP32-H2 Supermini is a compact, low-power wireless module powered by the Espressif ESP32-H2 System-on-Chip (SoC). Designed for space-constrained IoT applications, it integrates a 32-bit RISC-V core, Bluetooth 5.2 Low Energy (BLE), and IEEE 802.15.4, supporting Thread, Zigbee, and Matter protocols. This module is perfect for smart home devices, wearables, and other applications requiring reliable, energy-efficient wireless connectivity. This KiCad library provides accurate symbols, footprints, and 3D models to simplify integration into your projects.

Importing Symbols and Footprints into KiCad (Simplified Steps)

1. Download the Library:

   • Download or clone the ESP32-H2 Supermini KiCad library files (symbols: .lib, footprints: .kicad_mod).

2. Open KiCad:

   • Launch KiCad's Project Manager.

3. Add Symbol Library:

   • Go to "Preferences" -> "Manage Symbol Libraries."
   • Click the folder icon to add a new library.
   • Navigate to the downloaded .lib file and select it.
   • Click "OK."

4. Add Footprint Library:

   • Go to "Preferences" -> "Manage Footprint Libraries."
   • Click the folder icon to add a new library.
   • Navigate to the folder containing the downloaded .kicad_mod files and select it.
   • Click "OK."

5. Use the Components:

   • In the Schematic Editor, click "Add Symbol" and search for the ESP32-H2 Supermini symbol.
   • In the PCB Editor, click "Add Footprint" and select the corresponding footprint.

ESP32-H2 Supermini Pinout Explanation
