Raspberry Pi 4 model Bs arriving with newer 'C0' stepping
Owing to a mishap with the Pi 4 model B I use for testing—more on how Red Shirt Jeff ruined that board later this week—I had to go buy a new Pi 4 last week.
The local Micro Center only had the 8 GB model in stock, so I went a little over budget and bought it. When I arrived home, I checked the board, and noticed a bit of a difference on the Broadcom SoC:
Can you spot it? The model number of the BCM2711 chip on this board is
2711ZPKFSB06C0T, which is the same as the chip found on the Pi 400.
This is a newer stepping of the original Pi 4 model B chip, which has the model number
2711ZPKFSB06B0T. The difference is the third-to-last character, the C versus the B.
