Dual-band wireless LAN and Bluetooth are provided by the Cypress CYW43455 “combo” chip, connected to a Proant PCB antenna similar to the one used on Raspberry Pi Zero W. Compared to its predecessor, Raspberry Pi 3B+ delivers somewhat better performance in the 2.4GHz band, and far better performance in the 5GHz band

Previous Raspberry Pi devices have used the LAN951x family of chips, which combine a USB hub and 10/100 Ethernet controller. For Raspberry Pi 3B+, Microchip have supported us with an upgraded version, LAN7515, which supports Gigabit Ethernet. While the USB 2.0 connection to the application processor limits the available bandwidth, we still see roughly a threefold increase in throughput compared to Raspberry Pi 3B.

The Raspberry Pi model 3 B+ Specs

  1. SOC: Broadcom BCM2837B0, Cortex-A53 (ARMv8) 64-bit SoC
  2. CPU: 1.4GHz 64-bit quad-core ARM Cortex-A53 CPU
  3. RAM: 1GB LPDDR2 SDRAM
  4. WIFI: Dual-band 802.11ac wireless LAN (2.4GHz and 5GHz ) and Bluetooth 4.2
  5. Ethernet: Gigabit Ethernet over USB 2.0 (max 300 Mbps). Power-over-Ethernet support (with separate PoE HAT). Improved PXE network and USB mass-storage booting.
  6. Thermal management: Yes
  7. Video: Yes – VideoCore IV 3D. Full-size HDMI
  8. Audio: Yes
  9. USB 2.0: 4 ports
  10. GPIO: 40-pin
  11. Power: 5V/2.5A DC power input
  12. Operating system support: Linux and Unix

Key Improvements from Pi 3 Model B to Pi 3 Model B+

  • Improved compatibility for network booting
  • New support for Power over Ethernet
  • Processor speed has increased from 1.2Ghz on Pi 3 to 1.4Ghz
  • New dual-band wireless LAN chip, 2.4Ghz and 5Ghz with embedded antenna
  • Bluetooth 4.2 Low Energy
  • Faster onboard Ethernet, up to 300mbps speed

The only downside

The Gigabit Ethernet is a nice upgrade. However, the storage and network share the same bus. So you will not get full Gigabit speed. In other words Gigabit connectivity at a theoretical maximum throughput of 300Mb/s. But, you can’t get everything for $35.

Raspberry PI 3 model B+ pricing

The price is same as the existing Raspberry Pi 3 Model B:
  1. USD – $35

  1. […] For started with the Raspberry Pi as a hacking platform. You’ll need a few key components to getting the Pi up and running. Initially, you’ll need access to another computer to burn your Kali image to an SD card. Aside from the Pi 3 B+ itself, a good power adapter is necessary to power the Pi. The Pi takes a micro USB power cord, and the CanaKit beginner kit version of the Pi includes an appropriate adapter. In general, a dedicated 2.4-amp power supply is the best way to go. Next, you’ll need an SD card to put the operating system on. There are a lot of available options. But you should opt for a faster SD card with 16 GB of space. In particular, we recommend SanDisk Extreme and SanDisk Extreme Plus. You can get away with 8 GB, but things will be tight. To interact with the Pi, you’ll need a keyboard and mouse. It’s easiest to use a wireless keyboard and mouse combination like the Rii Mini Wireless Keyboard with Mouse Touchpad Remote Control, although we recommend avoiding the Bluetooth ones at all cost. They do not work well with Kali and take forever to configure. For started you’ll need a Kali-compatible wireless network adapter. After testing many, we were pleased with the performance of Panda Wireless network adapters, in particular, because of their small size and 2.4/5 GHz capabilities. For discreet Wi-Fi hacking, we recommend the PAU05 for 2.4 GHz or the PAU07 for 2.5 and 5 GHz. If you want to connect a directional or high-gain antenna to the adapter, the PAU06 is great for 2.4 GHz hacking, while the PAU09 is a powerful dual-band adapter with two swappable antennas. Finally, we recommend beginners include a Hak5 USB Rubber Ducky running the Twin Duck firmware. The Twin Duck firmware allows us to mount the Rubber Ducky as USB mass storage. Which means we can write and encode Ducky Script on our Pi with the Rubber Ducky plugged in. While the Rubber Ducky doesn’t ship with the Twin Duck firmware, it can easily be flashed.
