ROCK 4 SE, another Raspberry Pi Replacement

Posted by Mihai Beffa on

ROCK 4 is a single board computer developed by OKdo Technology in collaboration with Radxa. According to the manufacturer: 

  • ROCK 4 SE - a robust, versatile special edition single-board computer  
  • Based on a high-performing Hexa-core Rockchip RK3399-T processor 
  • big.LITTLE™ Arm® Dual Cortex-A72® CPU, Quad-core Cortex-A53 and Arm Mali™ - T860MP4 GPU 
  • Available in a 4GB 64bit LPDDR4 RAM option 
  • Expandable with eMMC module or SSD through m.2 connector  
  • Onboard RTC, WiFi, Bluetooth, Antenna, Audio jack (headphone and headset), 4K HDMI port 

It has many more interesting features, and you can read about it here:

ROCK 4 looks very much like a Raspberry Pi. It has the same form factor, the same USB and ETH connectors and a pin compatible GPIO expansion port. It lists $75 quantity one, with possible quantity discounts. Yet at this time there is a major difference between ROCK 4 and Raspberry Pi. It is in stock.

We decided to test it with our products. Since all our cards use only the I2C port to communicate with Raspberry, we were pretty confident it will work. 

Since this is a Linux box, our programs compile and run without a glitch. We tested several of our cards and could not find any flaws. 

Until the Raspberry Pi is back at advertised prices, and more importantly back in stock, consider the ROCK 4 for all your projects.
