Raspberry Pi LED GPIO Test Board
Now available from PMD Way is this handy GPIO LED test HAT, with free delivery.
The 40-way HAT connector and inline header pins as shown are included, but not soldered to the board. So when fitted to your Raspberry Pi, you can easily monitor the GPIO status of your activities.
The LEDs are active LOW, that is when the GPIO is off, the LED is on. And vice-versa. They are laid out on the HAT in the same pattern as the GPIO pins for easy reference.

Use the options menu to select between red, green and blue LEDs.
