Electronics Calculators

This category is in development. The following tools are planned and will be added with the same 3GPP/IPC-grade validation as the RF tools:

• PCB trace current / width (IPC-2221)
• Voltage divider and resistor power
• RC time constant and LC resonance
• LED series resistor and battery runtime
• I2C pull-up calculation

No formulas are published here until each is implemented and unit-tested, to avoid misleading values.
