Kyohritsu Electronic Industry Raspberry Pi 4 Model B Single Board Computer with 8GB SD Card and Raspberry Pi OS Pre-Installed

This set includes the Raspberry Pi 4 and an SD card with the latest OS written to it.
The latest generation of the single-board computer Raspberry Pi, the Raspberry Pi 4 Model B, is here!
While maintaining the same board size as previous models in the series, the new model boasts major performance improvements, including an ARM Cortex-A72 quad-core CPU and 4K display output, making learning programming and building embedded systems more convenient and flexible.
Wi-Fi and Bluetooth have obtained the necessary technical approval for use in Japan.
The latest OS, "Raspberry Pi OS (32-bit) with Desktop and Recommended Software," is already installed on the SD card (microSD), so simply inserting this product into your Raspberry Pi will immediately start up the OS.
[SD card product overview]
This is an SD card with the latest OS for Raspberry Pi written on it.
Installing an OS on a Raspberry Pi requires a separate PC and software,
The process of getting the Raspberry Pi up and running takes some time, including installation.
If you're not used to it, it can be a surprisingly difficult task.
This product comes with the latest OS, "Raspberry Pi OS (32-bit) with Desktop and Recommended Software," pre-installed on the SD card (microSD), so simply inserting the product into your Raspberry Pi will immediately start up the OS.
This will free you from the hassle of startup work.

[Features]
CPU
The CPU core of the Raspberry Pi 4 Model B has been upgraded from the ARM Cortex-A53 to the Cortex-A72, improving processing performance per clock. The operating clock speed has also been increased from 1.4GHz to 1.5GHz. Most programs will run as is.
memory
The Raspberry Pi 4 Model B comes with 1GB of main memory, the same as the previous Raspberry Pi 3 Model B+/B, as well as versions with expanded memory of 2GB, 4GB, and 8GB.
Ethernet (wired LAN)
The previous Raspberry Pi 3 Model B+ had a Gigabit Ethernet-compatible LAN controller connected via USB 2.0, which limited the theoretical maximum transfer speed to 300 Mbps. However, the Raspberry Pi 4 Model B has a changed controller and connection interface, which enables even faster transfer speeds.
Bluetooth (near field communication)
The Raspberry Pi 4 Model B now supports the Bluetooth version 5.0 standard, improving communication speed and distance.
HDMI video output
The Raspberry Pi 4 Model B now supports HDMI video output at 4K (3,840 x 2,160) resolution at 60 frames per second thanks to the enhanced graphics performance of the SoC. It also comes equipped with two HDMI connectors, allowing dual-screen output. The connector shape has been changed from full-size HDMI (Type A) to Micro HDMI (Type D).
case
The Raspberry Pi 4 Model B has the same board size as the previous Model B series, but there are changes to the connector types and layout, so depending on the case structure, products for the previous model may not be compatible.
Internal Interface
The internal interfaces of the Raspberry Pi 4 Model B, such as the GPIO pin header, CSI camera port, and DSI video port, remain unchanged from the Pi 3/2/B+.
power supply
The power input connector for the Raspberry Pi 4 Model B has been changed from USB Type B Micro (micro USB) to Type C. Also, because power consumption has increased with the improved performance, it is recommended to use a power supply capable of outputting 3A.
*Please note that the SD card (microSD) may differ in manufacturer name and whether it comes with or without an SD card conversion adapter depending on when it was installed.
※Please note:
*Please note that the OS version may change over time.
*Please note that users are free to upgrade their OS if necessary.
*Some product contents may change depending on the arrival date. *Set contents may change without notice. *Wi-Fi and Bluetooth have obtained the technical standards required for use in Japan. *[Points to note when purchasing Raspberry Pi 4]
*Please prepare a new power cable for the Raspberry Pi 4* Starting with the Raspberry Pi 4, power is provided via a USB C connector.
* Conventional AC adapters cannot be used. Please use the "AC adapter DC5V 3A (USB-C) / UU318-0530."
*Please prepare a new HDMI cable for the Raspberry Pi 4* With the Raspberry Pi 4, the video output has changed from HDMI to micro HDMI.
* Conventional HDMI cables cannot be used. Please use the "HDMI Cable AD (micro) 1m [RoHS] / 2HDMI-10M."
*Please prepare a case for the Raspberry Pi 4.
*The power and HDMI connectors have changed since the Raspberry Pi 4.
* Conventional cases cannot be used, so please use the "Raspberry Pi 4 case."
*A fan is essential for high-load processing, so please prepare a new one* The Raspberry Pi 4 has significantly improved performance, but in exchange, it generates very high temperatures.
*When high CPU power processing is required, such as deep learning or video processing, be sure to take heat countermeasures such as using a fan and heat sink to ensure the device performs at its best.
