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.
