Remappable Pin Table

This "Remappable Pin Table" wiki page provides pin mappings and functionality for various microcontrollers and development boards, allowing users to understand the input/output pin assignments and specific features available on each.

Arduino Uno

Lists pin numbers and corresponding port bit, functions like analog input, power, ground, reset, USART (serial communication), SPI (serial peripheral interface), I2C (inter-integrated circuit), external interrupts, and PWM (pulse-width modulation). Detailed breakdown of pin configurations for specific functions like communication protocols and control signals.
