Electronics MCP Servers
This server gives Claude direct access to 14 electronics engineering tools split across resistor decoding, capacitor calculations, and GPIO pinouts. You can decode four-band resistor color codes, calculate RC time constants and resonant frequencies, or look up which pins support PWM, ADC, I2C, and SPI on ESP32, Arduino UNO, and STM32 Blue Pill boards. It'll even generate ASCII pinout diagrams and check for pin conflicts. Helpful when you're prototyping circuits and need quick reference data without leaving your conversation or switching to datasheets.

Electronics MCP Servers
A comprehensive Model Context Protocol (MCP) server providing 14 electronics engineering tools across 3 domains.
Installation
pip install electronics-mcp-servers
Testing & Verification
After installation, verify the package is working:
Test with uvx (recommended for MCP clients)
# Alternative: Test individual servers
uvx --from electronics-mcp-servers resistor-decoder
uvx --from electronics-mcp-servers capacitor-calc
uvx --from electronics-mcp-servers gpio-reference
Test with pip install
# After pip install, test the CLI
electronics-mcp-servers --version
# Or test individual tools
resistor-decoder --help
capacitor-calc --help
gpio-reference --help
