Raspberry Pi 4 4GB is upgraded with Latest High-Performance Quad-Core 64-bit Broadcom 2711, Cortex A72 processor clocked at 1.5GHz speed. Which is design to use 20% less power or offer 90% greater performance than its old version. Hardware upgrade on Pi4 developed for more faster performance not only the loading time with all new 1GB/2GB and 4GB LPDDR4 SDRAM variants but also in connectivity with Dual-band 2.4GHz and 5GHz, 802.11 b/g/n/ac wireless LAN and PoE capability via a separate PoE HAT. Addition to its USB 3.0, improve the transfer speed by 10x than USB 2.0 to provide you significantly faster true Gigabit internet experience.
These is perfect Raspberry Pi 5 Black ABS Compact Case With Fan size 40mm*40mm*10mm for sufficient air circulation.
Fan is already fitted in case with screw.
At the heart of the Raspberry Pi Zero W is a 1GHz BCM2710A1 with 64-bit ARM Cortex-A53 CPU with 512MB RAM. Quite frankly, this Pi is about four times faster than the original Raspberry Pi and is only a fraction of the cost of the current RPi3.
Maximum effective distance up to 150mm, Less than 100ms decoding time, Support external antenna, Uart interface, Support EM4100 compatible read-only or read/write tags, Small outline design
