• CPU: 900 MHz quad-core ARM Cortex A7 (ARMv7 instruction set)
• GPU: Broadcom VideoCore IV @ 250 MHz
• More GPU info: OpenGL ES 2.0 (24 GFLOPS); 1080p30 MPEG-2 and VC-1 decoder (with license);
  • 1080p30 h.264/MPEG-4 AVC high-profile decoder and encoder
• Memory: 1 GB (shared with GPU)
• USB ports: 4
• Video input: 15-pin MIPI camera interface (CSI) connector
• Video outputs: HDMI, composite video (PAL and NTSC) via 3.5 mm jack
• Audio input: I²S
• Audio outputs: Analog via 3.5 mm jack; digital via HDMI and I²S
• Storage: MicroSD
• Network: 10/100Mbps Ethernet
• Peripherals: 17 GPIO plus specific functions, and HAT ID bus
• Power rating: 800 mA (4.0 W)
• Power source: 5 V via MicroUSB or GPIO header
• Size: 85.60mm × 56.5mm
• Weight: 45g (1.6 oz)

USB-to-LAN adapters are listed here.

Download at least IPFire 2.21 (Flash Image) and flash it to an MicroSD card.

Note!

• The ARM flash image is configured for serial console at default
• If using HDMI output and USB Keyboard edit the uENV.txt file and change SERIAL-CONSOLE=ON to OFF.

After flashing the SD card install it into the Raspberry Pi, connect the cables and power supply, and power it up. At the start of booting you'll see:

Net:   No ethernet found.
starting USB…
USB0:  Core Release: 2.80a
scanning bus 0 for devices…

The Raspberry Pi 2 Model B (Raspi 2B) will normally boot within xx seconds.

Note!
If the IPFire sits for more than 3 to 4 minutes it may be trying to locate a driver for an unknown USB device. Unplug the unknown device and reboot the Raspberry Pi.

Once the Raspi 2B is fully booted begin to follow the steps here.

Note!
In the IPFire setup Extended Network Menu the on-board Ethernet port is known as usb: Standard Microsystems Corp. SMSC95. And the wireless/WiFi is known as sdio: brcmfmac.
