بورد رسپبری پای 3 Raspberry Pi 3 Model B+ UK ساخت انگلستان
Welcome to the Pi Family
Here is what the new Raspberry Pi looks like :
The three most noticeable physical differences are :
- Metal cover with Pi logo on wireless circuitry
- Metal heat spreader on main CPU
- 4-pin Power over Ethernet header
Raspberry Pi 3 B+ Specifications
The Pi 3 Model B+ technical specifications are shown below :
- Broadcom BCM2837B0 chipset
- 1.4GHz Quad-Core ARM Cortex-A53, 4 cores
- 64 bit CPU
- 1GB RAM
- 4 USB 2.0 ports (via LAN7515)
- Gigabit Ethernet (via LAN7515, max speed 300Mbps)
- PoE (power over Ethernet)
- 40 pin header (26 GPIOs)
- MicroUSB power connector
- Dual-band (2.4GHz and 5GHz) 802.11ac Wireless LAN and Bluetooth 4.1 (Bluetooth Classic and LE)
- CSI camera interface
- DSI connector for official screen
- 3.5mm jack connector supporting stereo audio and composite video
- 2-pin reset header
- Micro SD socket
The most notable differences between the Pi 3B+ and the Pi 3B are
- Increased clock speed to 1.4GHz
- Power over Ethernet support via new header
- Gigabit Ethernet although max speed is 300Mbps
- Increased WiFi performance in two bands
- Improved PXE network and USB mass-storage booting
- Improved thermal and power management (via MaxLinear MxL7704)
- Heat spreader (the shiny square of metal on CPU)
- Better FCC compliance due to metal shield (with Pi logo)
The heart of the Pi 3 B+ is the BCM2837B0 running with a clock speed of 1.4GHz. This is an improvement over the Pi 3’s 1.2GHz although the number of cores remains the same at 4.
The memory remains unchanged at 1GB.
The number of USB ports remains unchanged with 4 full-sized USB 2.0 ports on the right hand-side of the board.
The Ethernet port now support Gigabit network connections and this will be welcomed by many users who have been asking for this feature for years. The new model will also support power over Ethernet with some additional hardware. Due to limitations in the the implementation the speed is limited to 300Mbps.
However the overall network throughput is now apparently three time better which is good news for any application that needs to shift data including network storage devices or media centres.
The ceramic antenna has been replaced with a resonant cavity design as seen on the Pi Zero W.
Video and Audio Output
Video output includes HDMI via a full-sized HDMI connector and composite video via the 4-pole 3.5mm jack.
Stereo audio is still available via the HDMI connector and 4-pole 3.5mm jack as in the Pi 3.
The power connector is still a microUSB socket. Power consumption is higher and estimates suggest it draws 170-200mA more than a Pi 3.
The physical size of the Pi 3 B+ remains unchanged with overall dimensions of 85mm x 56mm x 17mm.
Raspberry Pi 3 B+ GPIO Header
The 40-pin header used in this model is identical to previous generations so should be compatible with all hardware that works with the A+,B+,Pi 2 and Pi 3.
