QuadCore Raspberry Pi 4
From this article, the Raspberry Pi 4’s USB-C power port was designed outside of official USB-IF specifications, making it incompatible with many USB-C chargers and/or power supplies. You can read more about from the link above and the information gathered to come to such a conclusion was done by a well known Google engineer, Benson Leung.
The raspberry Pi is a collection of small computer boards put together in a simplistic way to create the foundation of a computer system. The Raspberry Pi (also known as RPi) was released back in Feb of 2012 in the United Kingdom. The original intent of the RPi was to develop a low cost and simplistic computer which students could learn and develop.
The original model became far more popular than anticipated, and started selling outside its target market for uses such as robotics. It does not include peripherals (such as keyboards and mice) or even come inside a case. Literally a bare-bones product.
To give you an idea of the popularity, the RPi products have sold over 19 million units between its release in 2012 to the end of fiscal year 2018. This makes the RPi one of the best-selling computers in the world, although a computer with limited resources. Until now.
This week the Raspberry Pi Foundation has released the Pi 4. This is one hell of a great product. Check out these specifications:
- A 1.5GHz quad-core 64-bit ARM Cortex-A72 CPU (~3× performance)
- 1GB, 2GB, or 4GB of LPDDR4 SDRAM
- Full-throughput Gigabit Ethernet
- Dual-band 802.11ac wireless networking
- Bluetooth 5.0
- Two USB 3.0 and two USB 2.0 ports
- Dual monitor support, at resolutions up to 4K
- VideoCore VI graphics, supporting OpenGL ES 3.x
- 4Kp60 hardware decode of HEVC video
- Complete compatibility with earlier Raspberry Pi products
In addition to the hardware improvements, the Raspberry Pi Foundation says the new PC will have an “extensively modernized user interface” including an updated Chromium 74 web browser. They’ve also moved from USB micro-B to USB-C for our power connector. This supports an extra 500mA of current, ensuring we have a full 1.2A for downstream USB devices, even under heavy CPU load.
The new boards are available to order now.
In the past, folks have tried running Windows on the Raspberry Pi platform, but the performance was slow, as expected. However; with this new configuration we’d like to hear who’s tried it and how was the performance (send email to gmo @ getusb dot info)
