Board revision codes in firmware
The following commandline will print a code to show which revision you have:
cat /proc/cmdline | awk -v RS=" " -F= '/boardrev/ { print $2 }'
The related blog post provides source code to determine the board revision in different programming languages.
Code values are shown in the table below:
| Code | Model name | New Features | GPIO changes |
|---|---|---|---|
| 0x2 | Model B Rev 1, 256MB RAM | (P2) JTAG pins, no mounting holes | Pin3=GPIO0, Pin5=GPIO1, Pin13=GPIO21, I2C-0 |
| 0x3 | Model B Rev 1, 256MB RAM | no polyfuses, no mounting holes | Pin3=GPIO0, Pin5=GPIO1, Pin13=GPIO21, I2C-0 |
| 0x4 (Sony) | Model B Rev 2, 256MB RAM | mounting holes | Pin3=GPIO1, Pin5=GPIO2, Pin13=GPIO27, I2C-1, 8 extra IO pads (P5) |
| 0x5 (Qisda) | |||
| 0x6 (Egoman) | |||
| 0x7 (Egoman) | Model A, 256MB RAM | mounting holes | Pin3=GPIO1, Pin5=GPIO2, Pin13=GPIO27, I2C-1, 8 extra IO pads (P5) |
| 0x8 (Sony) | |||
| 0x9 (Qisda) | |||
| 0xd (Egoman) | Model B Rev 2, 512MB RAM | mounting holes | Pin3=GPIO1, Pin5=GPIO2, Pin13=GPIO27, I2C-1, 8 extra IO pads (P5) |
| 0xe (Sony) | |||

Several different minor hardware versions/revisions RaspberryPi Boards have been found probably from different assembly lines. Try to identify your board for better troubleshooting and update it if you have one which is not mentioned.
