description	Raspberry Pi hardware interfacing: GPIO, I2C, SPI, UART, and Python programming for SBC hardware.

Goal: Interface hardware peripherals (sensors, actuators, radios) with a Raspberry Pi running a standard Linux OS (Raspberry Pi OS).

The 40-pin GPIO header provides multiple buses.

Levels: GPIO logic is 3.3V. Connecting 5V signals directly will destroy the Pi.
I2C: Pins 3 (SDA) and 5 (SCL). Requires enabling via raspi-config. Built-in pull-up resistors (1.8kΩ) exist on these pins.
SPI: Pins 19 (MOSI), 21 (MISO), 23 (SCLK), 24 (CE0), 26 (CE1).
UART: Pins 8 (TX) and 10 (RX). Usually mapped to /dev/serial0 (disables Bluetooth console on Pi 3/4).

Prefer gpiozero for simple UI/sensors and smbus2 or spidev for deep bus control.

sudo apt install i2c-tools
i2cdetect -y 1

from smbus2 import SMBus
with SMBus(1) as bus:
    # Read a byte from device 0x48, register 0x00
    b = bus.read_byte_data(0x48, 0)

Power: The 5V pins bypass the polyfuse. Modulating heavy loads (motors) requires an external relay/MOSFET and separate power supply.
Real-Time Limits: Linux is not a Real-Time OS. Fast bit-banging (like NeoPixels or strict timing protocols) will jitter unless offloaded to the PWM/DMA controllers or a co-processor (like an Arduino/Pico).
