The processor stepping (revision) is B0 (the heat spreader says 2711ZPKFSB06B0T).It seems to be stable at 2.0 GHz with overvoltage6 it'll hang during stress tests at 2.15 GHz, and the Raspberry Pi OS desktop will not load at all at 2.2 GHz. Your script returns the following on my Pi4B. I just acquired a Raspberry Pi 4 Model B with 4GB RAM. $ cat /proc/cpuinfoįeatures : half thumb fastmult vfp edsp neon vfpv3 tls vfpv4 idiva idivt vfpd32 lpae evtstrm crc32 # H 25-25 WarrantyVoidNew ('' 'warranty void - Post Pi2') # G 24-24 WarrantyVoidOld ('' 'warranty void - Pre Pi2') Identifying the stepping on your Pi 4 If you want to see if you have the newer revision to the BCM2711 SoC on your Pi, there are two ways. # F 23-23 EncodedFlag ('' 'revision is a bit field') # M 20-22 MemorySize ('256 MB' '512 MB' '1024 MB' '2048 MB' '4096 MB') The Raspberry Pi 4 has similar design and dimensions to its predecessors, but it’s an all-new platform, powered by a new processor, the Broadcom BCM2711B0.

So the script should output official information now. Both the old and new Raspberry Pi have 802.11ac Wi-Fi that can run on 2.4 GHz or 5-GHz bands. ROCK Pi 4 is a Rockchip RK3399 based SBC(Single Board Computer) by. MAC-address(es) = b8:27:eb:12:34:56 b8:27:eb:ab:cd:efĮDIT: The documentation was updated in the meantime, This is the documentation for ROCK Pi 4, written by Radxa Team with community contributions. I'd like to know what the RaspBerry Pi 4 codes for ModelName,Processor and Memory are. The latest Pi, at the time of this writing, is the Raspberry Pi 4 (189.95 at Amazon) (Opens in a new window), which rocks a 1. For Raspberry Pi 4 B revisions 1.1 and 1.2 only. Chapter 5 provides more information on identifying your Raspberry Pi. Alternatively, look for this unidentified transistor thingie that seems to be new on the Rev 1.To enhance my bash script decoding the Revision returned by cat /proc/cpuinfo Diagram for connecting the USB-UART converter and Raspberry Pi 4 B. The additional Rev 2.0 header P5 is shown in Table 3-4. If the board is still in your hand or if you’re shopping for one and the store allows you to inspect it, you can look for the position of the WLCSP SD card voltage switch, which has been moved from behind the microSD card slot to the top corner. And the 'Model' will be listed as 'Raspberry Pi 4 Model B Rev 1.2'. If you’ve the new board, the ‘Revision’ section should read ‘c03112’. GPU: Broadcom VideoCore IV, OpenGL ES 2.0, 1080p30 h.264/MPEG-4 AVC. Sensor Video Webcam for Raspberry Pi Model A/B/B+, Pi 2, Raspberry Pi 3, 3B+, Pi 4B Ras Pi 4 Zero. Via CNX Software, if your Pi 4 is already up and running, the easiest way is to head to the command line and use the cat command (cat /proc/cpuinfo) to retrieve the CPU info. Model B (Revision 2.0) - Its a latest launched Raspberry Pi Revision 2 with 512MB. Raspberry Pi Camera, supports all revisions of the Pi. So, how can you tell if the Pi 4 you’ve bought recently has the updated Rev 1.2 design (here’s a shot of it on Imgur)? When putting together our emulation box in 2016, we tried to stick as close to the 60 asking price of the NES Classic. Well, The Register checked back with Upton last month and he has confirmed that the revised design has been sent to manufacturing and the new boards should have reached end users by now. Supply chain woes lead to a temporary Raspberry Pi 4 price hike.
At the time, Eben Upton, CEO of Raspberry Pi Ltd., said that a PCB revision would probably come at some point to fix the issue, but stopped short of providing an exact date. When the Raspberry Pi 4 Model B dropped last year, many users quickly found out that it had a USB-C issue that prevented the board from properly recognising certain power adapters. Note: This article was first published on 23 March 2020. Wikipedia has a good graphical summary of the various board designs: Raspberry Pi 1 model A+ revision 1.1: Raspberry Pi 1 model B and B+ revision 1.2: The Raspberry Pi 1 model B revision 2: The Revision 2 board has holes for an additional header next to the main header P1 and also there are now mounting holes.
