This page describe the difference in hardware of all rock hardware revisions.

Revision 2013.08.12(Engineering samples)

The first batch of radxa rock samples, also called radxa rock engineering samples, only 100pcs are made(Limited Edition :). Almost everything work fine on this revision. However there is still some small issue such as

  • The HDMI connector is too close to the SPDIF jack, may conflict with some big header of the HDMI cable
  • The UART can be damaged sometimes by some 5V TTL to USB cable (Warning: do use 3.3V TTL to USB cable)
  • The reset key is acted as POWER halt function, rebooting the board need to press the reset key and then the power key.
