+===== Expansion Header =====
+Der Expansionheader wird mit der "Hauptplatine" verbunden. Pin1 befindet sich an der "inneren" Seite des RasPi3, gegenüber der USB-Buchsen.
+Ersetzen durch : TLW-120-05-G-D
+Adapterplatine mit 2x SLW-120-01-G-D

-HDMI Buchsen auf RasPi3 und Converterplatine durch Samtec ZF5S-25-01-T-WT und FJH-25-D-02.50-4 Flachbandkabel ersetzen (25 Pol statt 23 Pol, da Kabel nur in 25 Pol verfügbar).

+===== RasPi 3 SD Card Image =====
+Note: The current installation uses the 32-bit Raspberry Pi 2 armv7h root filesystem. This will be changing eventually to use our AArch64 repository to take full advantage of the ARMv8 Cortex-A53 cores. If you want an AArch64 system, consider the ODROID-C2.
+Also note: The Raspberry Pi 3 has higher power requirements than the Raspberry Pi 2. A power supply rated at 2.5A is the official recommendation. Using an insufficient power supply will result in random, inexplicable errors and filesystem corruption.
+Replace sdX in the following instructions with the device name for the SD card as it appears on your computer.
+- Start fdisk to partition the SD card:
+    fdisk /dev/sdX
+- At the fdisk prompt, delete old partitions and create a new one:
+        Type o. This will clear out any partitions on the drive.
+        Type p to list partitions. There should be no partitions left.
+        Type n, then p for primary, 1 for the first partition on the drive, press ENTER to accept the default first sector, then type +100M for the last sector.
+        Type t, then c to set the first partition to type W95 FAT32 (LBA).
+        Type n, then p for primary, 2 for the second partition on the drive, and then press ENTER twice to accept the default first and last sector.
+        Write the partition table and exit by typing w.
+- Create and mount the FAT filesystem:
+    mkfs.vfat /dev/sdX1
+    mkdir boot
+    mount /dev/sdX1 boot
+- Create and mount the ext4 filesystem:
+    mkfs.ext4 /dev/sdX2
+    mkdir root
+    mount /dev/sdX2 root
+- Download and extract the root filesystem (as root, not via sudo):
+    wget http://archlinuxarm.org/os/ArchLinuxARM-rpi-2-latest.tar.gz
+    bsdtar -xpf ArchLinuxARM-rpi-2-latest.tar.gz -C root
+    sync
+- Move boot files to the first partition:
+    mv root/boot/* boot
+- Unmount the two partitions:
+    umount boot root
+- Insert the SD card into the Raspberry Pi, connect ethernet, and apply 5V power.
+ Use the serial console or SSH to the IP address given to the board by your router.
+ Login as the default user alarm with the password alarm.
+ The default root password is root.
