Radxa's new version of the Rock Pi 4, the Model C, is finally orderable. The Rock Pi 4 Model C has an M.2 connector for NVMe storage and is available for as little as US$59. The SBC is available with a hexa-core processor and 4 GB of RAM.

The Rock Pi 4 Model C is now available to order. The single-board computer (SBC) is produced by Radxa and is available to order from retailers like AllNetChinaAliExpress and Amazon. We should point out that the Rock Pi 4 Model C is significantly cheaper on AllNetChina, where it costs US$59. By contrast, the device costs US$99.99 and US$109.99 on AliExpress and Amazon, respectively.

The SBC is based on a Rockchip RK3399 processor that features two ARM Cortex-A72 cores and four ARM Cortex-A53 cores. This is supplemented by an ARM Mali-T864 GPU that supports modern APIs like OpenGL ES 3.2 and Vulkan 1.0. The Rock Pi 4 Model C also has 4 GB of RAM, a micro HDMI 2.0a port and a mini DP 1.2 port for high-resolution video output. Both connectors can only output in up to 60 Hz, though.

One of the changes for the Model C is its M.2 socket. The socket supports 4-lane NVMe SSDs and is complemented by 4 MB of SPI flash for booting NVMe drives. The SBC requires an expansion board for connecting NVMe drives, though. As with many any SBCs, the Model C has a 40-pin header for UART, SPI, I2C, GPIO and power. The Model C can also be powered via its Type-C port or Ethernet.

CNX Software opines that the Model C may support the same firmware images as the Model A and Model B, albeit without mini DP support. The Model C is seemingly compatible with existing Rock Pi 4 accessories too.
