Why it exists

Replace a messy stack of modules with one documented board.

Many Raspberry Pi hardware projects need extra GPIO, analog inputs, serial communication, USB ports, and safer power handling. The Top HAT consolidates those needs into one board designed for prototyping, automation, learning, and real-world testing.

ADC

Read analog sensors

Use the 3-channel 12-bit ADC for sensors that Raspberry Pi cannot read directly through GPIO alone.

485

Connect industrial-style devices

Built-in RS-485 support helps builders experiment with longer-range wired communication.

I/O

Expand real projects

16 GPIO expansion pins and four USB 2.0 ports reduce module stacking and make builds cleaner.
