ODROID-N2
N2 PCB revision and LOT number history
| LOT(Year+Month) | PCB Revision | Description |
| 1901 | rev0.3 20190117 | Sample |
| 1903 | rev0.4 20190307 | 1st Mass Production |
| 2006 | rev0.5 20200406 | N2+ |
| 2010 | rev0.5 20200406 | As the ODROID-C4 board, the 3.3V(Pin#1) power rail of the 40pin expansion connector has been changed to be Always-ON in the shutdown mode. |
| 2011 | ||
| 2102 | rev0.5 20200406 | To lower the electrical stress to the GL3523 hub controller, the GL3523 power source has changed to 5V from 3.3V by using internal regulator. Mount a zero ohm resistor between the source and drain of Q1 instead of the FET As a negative side effect, the PWR red LED does dimly turn on even when the system turns off. This issue appears with the production batch of EL2102 only. |
| 2106 | rev0.6 20210121 | The power of GL3523 is completely isolated from the 3.3 V system power rail. Between the VDDOAO_3V3 and the VCC3V3 net, it was changed to integrated load SW instead of discrete PMOS FET. |
| 2111 | rev0.6 20210121 | The SPI flash memory manufacturer has been changed to XTX from MXIC, and the firmware version of Petiboot been updated to 20211112 to work with the XTX flash memory. |
| 2202 | rev0.6 20210121 | Due to the semiconductor shortage, the maximum DC input voltage was lowered from 18V to 16V to use to FirstSilicon's FC6800 from FC3470. |
| 2208 | rev0.6 2020517 | the rev0.6 2020121 version and schematic are the same, but the footprint of the low acoustic capacitor on the PCB has been changed. |
We did not change the PCB revision because any key features were not changed nor added.
How to check year and month with the production LOT number

We recommend powering the ODROID-N2/C4 with a good quality 12V/2A power adapter. However, using a good quality 15V/4A power adapter is also OK if you already have one handy.
Note that 15V/4V is not necessary for the N2, N2+ and C4, 12V/2A is plenty enough. On the other hand 15V/4A is required for the HC4 and the H2 series because these boards may power mechanical hard drives.
