==Overview==
This G470 GPIO Test Terminal Block Breakout Board for Raspberry Pi is an easy-to-use expansion board designed to simplify wiring and connections for your Raspberry Pi projects. With labeled screw terminals for each GPIO pin, it provides a reliable way to connect external components without soldering, making it ideal for prototyping and development work. This breakout board is perfect for makers, hobbyists, and developers looking to simplify and improve the connectivity of their Raspberry Pi projects.
==Features==
* Model: G470
* Compatible with Raspberry Pi 4B / Pi 3B+ / Pi 3B / Pi Zero
* Based on Raspberry Pi 40pin design, suitable for beginners of Raspberry Pi
* Lead out all GPIO function pins, easy and convenient access to the Raspberry Pi GPIO
* On-board ADDA chip, can read AD signals, output DA signals
* LED shows the status information of GPIO Pins. When the GPIO pin is operated and effective in the terminal, the LED matrix on the right side of the terminal will display the status of the GPIO pin
* On-board industrial terminal block female port, terminal with interface definition sticker. More beautiful and practical
==Packing List==
* 1 x Screw Terminal Block Breakout Board (Model: G470),
* 1 x Screws Pack

Ensure that I2C is on, and then restart the system.
sudo reboot
After restart, address 48 can be detected by I2C address detection command.
i2cdetect -y 1
