Raspberry Pi 4 Model B is the latest product in the popular Raspberry Pi range of computers. It offers ground-breaking increases in processor speed, multimedia performance, memory, and connectivity compared to the prior-generation Raspberry Pi 3 Model B+
What’s New in Raspberry Pi 4 B?
- 1GB/2GB/4GB Varients
- Quad-Core 64-bit Broadcom 2711, Cortex A72 Processor
- WLAN 802.11 b/g/n/ac (2,4 + 5,0 GHz)
- LAN RJ45 10/100/1000 Mbit (Gigabit LAN over USB 3.0)
- Operating Power 5V@3A via USB Type-C Port
- Dual-Display Micro HDMI Ports which supports H 265 Decode for 4K Video @60p
Though the Pi 4 has type C USB port for 5V 3A input power capacity, new Hardware on Pi 4 even required less power than the previous versions therefore old power adapter can provide plenty of power to the chip, Ethernet, and any USB add-ons you plug in on board. You need not to worry about power adapter as it will also work great with your old 5V 3A power supply Adapter, All you need is micro-USB B (F) to Type C (M) Adapter With upgraded hardware of Pi 4, you can still use all your favourite Raspbian or PIXEL software with this update. You must make sure to upgrade your Raspbian operatingsystem install to the latest version so that the firmware can support the new chips! Old SD cards from previous releases will not work without an upgrade!
- With one of latest Broadcom 2711, Quad-Core Cortex A72 (ARM V8-A) 64-bit SoC Clocked at1.5GHz processor improved power consumptions and thermals on the Pi 4+B means that the CPU on the BCM2837 SoC can now run at 1.5GHz, a 20% increase on the previous Pi 3 model (which at 1.2GHz).
- Hardware upgrade on Pi4 developed for more faster performance with all new 1GB/2GB and 4GB LPDDR4 SDRAM variants.
- Video performance on Pi 4 B is also upgraded with dual-display support at resolutions up to 4K via a pair of micro-HDMI ports, hardware video decode at up to 4Kp60 which supports H 265 Decode (4Kp60), H.264, and MPEG-4 decode (1080p60).
- A significant change on the Pi 4 B compared to the previous Pi 3 models is the inclusion of a new faster, dual-band wireless chip with 802.11 b/g/n/ac wireless LAN.
- The dual-band 2.4GHz and 5GHz wireless LAN enables faster networking with less interference and the new PCB antenna technology allow better reception.
- Latest 5.0 Bluetooth allows you to use a wireless keyboard/trackpad with more range than before without extra dongles, keeping things nice and tidy.
3.Enhanced Ethernet Connectivity:
- The Pi 4 B has significantly faster-wired networking with USB 3.0 technology, thanks to an upgraded USB/LAN chip, and you should see speeds that are 10x faster than on previous models of the Pi.
- The GPIO header remains the same, with 40 pins, fully backwards-compatible with previous boards as on the previous three models of Pi. However, it should be noted that the new PoE header pins may contact components on the underside of some HATs, like Rainbow HAT. Some standoffs will prevent any mischief from occurring though!.
