Raspberry Pi LED Status Indicator Info

led status infi
There are 5 status LED's on the Raspberry Pi board namely [OK, PWR, FDX, LNK, 10M]. FDX, LNK, 10M are connected to the LAN IC- LAN9512. So those 3 LED's will be present only on model B.

According to http://elinux.org/RPi_Hardware

D5(Green) - OK - SDCard Access (via GPIO16)
D6(Red) - PWR - 3.3 V Power
D7(Green) - FDX - Full Duplex (LAN) (Model B)
                                                      D8(Green) - LNK - Link/Activity (LAN) (Model B)
                                                      D9(Yellow) - 10M - 10/100Mbit (LAN) (Model B)

According to the datasheet the pins can also be programmed as GPIO, so these three LEDs could potentially be under software control, but I have not checked if the Linux drivers support this.


  1. I was very pleased to find this site.I wanted to thank you for this great read I definitely enjoying every little bit of it and I have you bookmarked to check out new stuff you post.

  2. It does sound that everybody is into this stuff recently. Don’t truly fully understand it however, nonetheless appreciate your attempting to describe it.
