If you have any questions, please feel free to contact us by email. 【Efficient Heat Dissipation】The Raspberry Pi 4b kit adopts three-layer high temperature-proof structure. Three heat sinks prevent the chip from overheating and short-circuiting, and prevents components from overheating. Cooling fans prevent the Raspberry Pi motherboard from overheating. High efficiency and heat resistance give you a safe and wonderful invention journey. 【Special Charging Upgrade】The usb - C 5V / 3.0A power charger included in this Raspberry Pi 4 Kit is equipped with a convenient switch. The voltage stability is strong during use. Automatic multi-circuit protection system to avoid short circuit, high temperature, over-current and over-voltage. 【ARM Cortex A72 】The raspberry pi 4 model b adopts the latest arm cortex-a72 architecture, which is also used in high-performance smartphones, and has evolved into a real pc. Cortex A72 has 15-instruction pipeline depth, compared to just 8 on the older model, and it also provides out-of-order execution so it’s not waiting for the output of one process to start on another. So, even at the same clock speed, Cortex-A72 processors will be significantly faster and use more power. 【Raspberry Pi 4 VS Pi 3】It offers ground-breaking increases in processor speed, multimedia performance, memory, and connectivity compared to the prior-generation Raspberry Pi 3 Model B+, while retaining backwards compatibility and similar power consumption. For the end user, Raspberry Pi 4 Model B provides desktop performance comparable to entry-level x86 PC systems.
