I received a Rock 4 SE from RS Components after waiting a year for a Raspberry Pi 4. My first impressions, i probably should have waited for the Pi 4. I’m not impressed with the Rock 4 SE 4.
Installing Ubuntu server was straight forward but past that the sheer lack of coherent information or complete documentation is frustrating to say the least. Joining the forum was a chore - tried 5 times to register with my Hotmail account only to find the Forum was blocked by Microsoft as spam, eventually used a different e-mail account. I had A few minor problems with the Ubuntu server install, searching the forums and FAQ i noticed several people with the same install issues, the responses from Radxa support were pathetic and a total waste of time.
Reading on the forum several people have received the SBCs with missing / fallen off resistors and posted pictures - Not a single response from Rock or Radxa. I have the feeling this is a case of trying to capitalize on Pi’s supply chain issues, this is fine and the product seems to have potential but it’s totally let down by poor support and documentation. If any one wants my opinion - wait for your Pi or get an older version.
