1 A T-shape Extension Board which extends the pins of Raspberry Pi and can be directly plugged into a breadboard
<br />2 Separate UART pins, convenient for logging into the Raspberry Pi by serial port
<br />3 All pins are labeled with BCM, those on the right sequenced by wiringPi
<br />4 The power and GND pins underneath can be plugged into the power (+) and ground (-) rails on the breadboard
<br />5 With a power indicator LED, and well-designed socket in case of inverse cable connection 
<br />Technical Details
<br />Introduction
<br />This T-shape extension board, as the name suggests, is to extend the GPIOs of a Raspberry Pi. Underneath the power and GND pins can be plugged into the + and   rails on a breadboard, making it easy and neat to connect. A filter capacitor is added between the power and GND for steady voltage output. With this T_Extension Board, you can make your experiments more conveniently and easily!
