Within the span of a few decades, computer technology has advanced from requiring entire rooms full of equipment to the fully functional computer boards that fit into the palm of our hands today. And Makers are living the dream as this technology becomes more accessible to anyone who wishes to tinker. Single board computers are powerhouses of multimedia functionality and operating systems on a small form factor which you can use in endless smart applications like custom laptop builds. But sometimes, the popular official Raspberry Pi boards are too hard to find, or you might have need for slightly better performance at similar cost. You need a rock-solid alternative, like Okdo’s Rock 4 SE Single Board Computer! The Raspberry Pi will always have a place in our hearts at DIYElectronics, but we are awestruck at this natural Raspberry Pi alternative.

The 4GB Okdo Rock 4 SE Single Board Computer was introduced as a perfect alternative to the Pi 4 model with very similar form factors and functionality. Of course, there’s one key difference. The Rock 4 SE Board utilises the Rockchip RK3399-T processor in replacement of the Raspberry Pi chip. This allows for more processing cores with 4GB 64-bit RAM of broader memory interfaces. A GPIO header of 40-pins is colour-coded and ready for your easy connections. The 4GB Okdo Rock 4 SE has enough computing power to rival sully sized computers with awesome key features.

What Awesome Key Features are Included in the Rock 4 SE 4GB Single Board Computer?

Within its small form factor, the Okdo Rock 4 SE 4GB Single Board Computer contains fantastic features that bring functionality to your electronics project. While “Pi” is missing from this board’s name, the similarities are hard to ignore. But even so, we must dig a bit deeper into the juicy details of the features at your fingertips:

  • Powerful Rockchip Processor – At the heart of the Rock 4 SE sits its very own high performing Rockchip RK3399-T processor that makes up the brains behind these little single board computers. This board contains two whole processing cores, the dual-core cortex A72 and quad-core cortex A53 CPU. With this brainpower, the Rockchip caters to many of the small bottle-necking problems that some chips suffer. You can step up your projects in terms of both processing speed, as well as complexity.
  • Large Storage Capacity – With 4GM RAM and multiple interfaces, the Rock 4 SE offers extensive storage capability. A Micro SD card slot, eMMA and M.2 are available on the board for your additional external storages, allowing even more functionality to you.
  • Real-Time Clock – Keeping time is a handy feature for any smart device to have. The onboard real-time clock accurately tells time even when the Rock 4 SE is offline or powered off. A connector is built onboard for an RTC battery. You can program your system for time-sensitive tasks and accurate triggers.
  • Multiple Connectivity Options – WiFi, Bluetooth 5.0, Gigabit Ethernet, USB and HDMI ports are all configured masterfully onto the Rock 4 SE for an array of connective capabilities. The ethernet or WiFi offers high speed internet connections while the USB and HDMI ports allow you to connect external components like a camera and display. On top of it all, a built-in antenna allows you to incorporate the Rock 4 SE into even more awesome applications.
  • Multimedia Functionality – The quad-core processor GPU of the Rock 4 SE is ideal for advanced multimedia applications. Gaming consoles or other high graphics applications require SBC’s with multimedia functionality. The Rock 4 SE board includes camera and display interfaces, a 4K HDMI port, and an audio output for high quality multimedia components.

Please Note: This model of the Okdo Rock 4 SE board is the 4GB RAM/64-bit version with WiFi and Bluetooth. If you are interested in the original Raspberry Pi 4, check out our stocks of Pi boards.
