Raspberry Pi 4
I have been waiting for the Raspberry Pi 4 to be in-stock since its release in June of 2019. I have been a little late on the pre-release purchase, but I have found a good price on a kit to get started on Amazon.
My 3B+ is being used as a RetroPie and I have no ideas on changing that because it's been very fun to have as a solid gaming station. I have been able to play all kinds of games that I had lost when I got rid of my old gaming stations. However, there is plenty of other projects that I want to make using the new and improved 4B model. Here are the specs from the 4B and I'm getting the 4GB version.
1. Broadcom BCM2711, Quad core Cortex-A72 (ARM v8) 64-bit SoC @ 1.5GHz
2. 1GB, 2GB or 4GB LPDDR4-3200 SDRAM (depending on model)
3. 2.4 GHz and 5.0 GHz IEEE 802.11ac wireless, Bluetooth 5.0, BLE
4. Gigabit Ethernet
5. 2 USB 3.0 ports; 2 USB 2.0 ports.
6. Raspberry Pi standard 40 pin GPIO header (fully backwards compatible with previous boards)
7. 2 × micro-HDMI ports (up to 4kp60 supported)
8. 2-lane MIPI DSI display port
9. 2-lane MIPI CSI camera port
10. 4-pole stereo audio and composite video port
11. H.265 (4kp60 decode), H264 (1080p60 decode, 1080p30 encode)
12. OpenGL ES 3.0 graphics
13. Micro-SD card slot for loading operating system and data storage
14. 5V DC via USB-C connector (minimum 3A*)
15. 5V DC via GPIO header (minimum 3A*)
16. Power over Ethernet (PoE) enabled (requires separate PoE HAT)
17. Operating temperature: 0 – 50 degrees C ambient
* A good quality 2.5A power supply can be used if downstream USB peripherals consume less than 500mA in total.
One last and great thing, the Raspberry Pi 4 Model B will remain in production until at least January 2026. That means there a lot of life planned for it and makers and builders alike can comfortably buy one knowing there is going to be support for many years to come. Enjoy Builders, I know I will.
