# Seeed Studio XIAO ESP32C3 (Component) ## Description 2-Channel Isolated Blast Gate Controller with Automotive-Grade Field IO and XIAO ESP32C3 Central Control ## Component Details - **Owner:** seeedstudio - **Created:** 11/7/2023 - **Last Updated:** 12/19/2024 - **Visibility:** Public - **Purchase Url:** https://www.seeedstudio.com/Seeed-XIAO-ESP32C3-p-5431.html - **Power_Planes:** Internal Layer 2, Internal Layer 3 - **Part Type:** Microcontroller - **XIAO_Power_Pin:** 5V pin from 5V rail as supply - **Stackup:** Standard 4 Layer - **Manufacturer Part Number:** 113991054 - **Ground_Fill_Rule:** Copper fill on Top and Bottom layers connected to GND net - **Connector_Orientation:** right-angle - **Datasheet URL:** https://files.seeedstudio.com/wiki/XIAO_WiFi/Resources/esp32-c3_datasheet.pdf - **Manufacturer Name:** Seeed Studio - **System Architecture:** ```mermaid graph LR A[12V Entry Protections] --> B[EMI Filter] B --> C[Buck Regulator] C --> D[XIAO ESP32C3] D --> E[Isolated High-Side Trigger Drivers] D --> F[Isolated Status Inputs] E --> G[8-Pin Micro-Fit Connector] F --> G ``` - **Keepout_Areas:** Define no-copper keepout zones around all connector pins and each test point. Ensure a minimum exclusion area of sufficient size to mitigate vibration-induced solder joint stress and to preserve ground plane continuity wherever possible. Intent: Enhance mechanical reliability and maintain EMI integrity by preventing copper flood encroachment under and around connectors/test pads. - **Used in:** 857 projects - **Stars:** 18 - **Forks:** 26 ## Distributor Pricing (qty 1) *Pricing shown for quantity 1.
