Damn my desk is a disaster....
Well I'm repairing server problems to assist @enginewitty and my @peakcoin relations
I took the evening to pin out my glorious Raspberry Pi 5

⚡ Notes:
- Power Input (if using GPIO) → Use Pin 2 or 4 (5V) + any GND.
- 3.3V Pins (1 & 17) → Output only, not safe for input power.
- UART → Pins 8 (TXD), 10 (RXD).
- I²C → Pins 3 (SDA), 5 (SCL).
- SPI → Pins 19, 21, 23, 24, 26.
- PCM/I²S → Pins 12, 35, 38, 40.
- GND → Pins 6, 9, 14, 20, 25, 30, 34, 39.
