Raspberry Pi 3 Model B+

Raspberry Pi 3B+ specifications

  • SoC: Broadcom BCM2837B0 1
  • CPU: Quad-core A53 (ARMv8) 64-bit @ 1.4GHz
  • GPU: Broadcom Videocore-IV
  • Network: Gigabit Ethernet (via USB channel), 2.4GHz & 5GHz 802.11b/g/n/ac Wi-Fi
    • gigabit at a theoretical maximum throughput of 300Mb/s, due to its use of a single USB channel.
  • Bluetooth: Bluetooth 4.2, Bluetooth Low Energy (BLE)
  • Storage: Micro-SD
  • GPIO: 40-pin GPIO header, populated
  • Ports: HDMI, 3.5mm analogue audio-video jack, 4x USB 2.0, Ethernet
  • Dimensions: 82mm x 56mm x 19.5mm, 50g

USB-to-LAN adapters are listed here.

Download the latest IPFire (Flash Image) and flash it to an MicroSD card.

The ARM flash image is configured for serial console at default
• If using HDMI & USB Keyboard: edit the uENV.txt file and change SERIAL-CONSOLE=ON to OFF
• If using the serial console: edit the config.txt file and add enable_uart=1 to the end

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 3 Model B+ (Raspi 3B+) will normally boot within 70 seconds. Once the Raspi 3B+ is fully booted begin to follow the steps here.

If the IPFire sits (forever) with just the IPFire logo (1 logo for each core), then see Note! above. The IPFire may using HDMI & Keyboard while configured for serial console.
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.

On-board Ethernet and WiFi

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.


Network 2

To perform these benchmarks, the Raspberry Pi IPFire box was connected... iperf3. gigabit ethernet.
