Rock Pi 4 Model C: NVMe and eMMC in a Raspberry Pi Layout


From the beginning revealed in October 2019, Rock Pi 4 Model C from Radxa has been difficult to follow purchase as of not long ago. CNX Software has clearly observed that the Rock Pi 4 Model C is direct open from $59.

Rock Pi 4 Model C is a course of action creamer, assessing 3.3 x 2.1 inch (85 x 54 mm) this board shares setup prompts from the Raspberry Pi 3 and 4 yet it has fairly more to it than a Raspberry Pi.

Rock Pi 4C Specifications

  • SoC – Rockchip RK3399 big.LITTLE Hexa-core processor with
  • CPU: 2x Arm Cortex-A72 @ up to 1.8 GHz, 4x Cortex-A53 @ up to 1.4 GHz
  • GPU: Mali-T864 with support OpenGL ES1.1/2.0/3.0/3.1/3.2, Vulkan 1.0, OpenVG1.1, OpenCL 1.1/1.2, DX11, and AFBC
  • VPU with 4K VP9 and 4K 10-bit H265/H264 decoding
  • 64-bit 4GB LPDDR4 @ 3200 Mbps (single chip)
  • eMMC module socket up to 128GB
  • Micro SD card slot up to 2TB
  • 4-lane M.2 NVMe SSD socket (expansion board required)
  • Micro HDMI 2.0a up to 4K @ 60 Hz
  • Mini DP 1.2 up to 2560 x 1440 @ 60 Hz
  • Audio – Via HDMI and 3.5mm audio jack
  • Camera – MIPI-CSI2 connector for camera up to 8MP
  • Connectivity – Gigabit Ethernet with PoE support (add on required), dual-band 802.11b/g/n/ac WiFi 5, Bluetooth 5.0 with on-board antenna
  • USB – 1x USB 3.0 host port, 1x USB 3.0 OTG port, 2x USB 2.0 host ports
  • Expansion – 40-pin I/O header with 1x UART, 2x SPI bus, 2x I2C bus,  1x PCM/I2S, 1x SPDIF, 1x PWM, 1x ADC, 6x GPIO, and power signals (5V, 3.3V, and GND)
  • Misc – RTC with connector for backup battery
  • Power Supply – Via USB-C port supporting USB PD 2.0 (9V/2A, 12V/2A, 15V/2A, or 20V/2A) and Qualcomm Quick Charge 3.0/.0 (9V/2A, 12V/1.5A)

The Rockchip RK3399 Hexa-center processor consolidates a twofold center Arm Cortex A72 1.8GHz, the tantamount A72 CPU as found in the Raspberry Pi 4, yet the Raspberry Pi has a quad place CPU running at 1.5GHz, so with fewer concentrates in any case more speed will there be a huge amount of multifaceted nature in execution? We should take a couple to get back some self-control of a unit for the test!

There are twofold presentation yields, downsized scale HDMI and smaller than normal DisplayPort giving 4K @ 60Hz and 2560 x 1440 @ 60Hz solely. The framework comes as four USB ports, two USB 3.0, two USB2.0, and Gigabit Ethernet, so Raspberry Pi 4 relationship, in a Raspberry Pi 3 plan. Inaccessible availability is 802.11 b/g/n/cooling WiFi 5 and Bluetooth 5.0 by strategies for an on-board assembling contraption, at any rate, there is an outside radio wire alliance. A 40 pin GPIO is available, offering access to UART, SPI, I2C, PCM/I2S, SPDIF, PWM, and an Analog to Digital Converter, something not found on the Raspberry Pi GPIO.

What is diverse about the Rock Pi 4 Model C is limit. Sure we have the normal microSD card space, in any case, we in addition have an eMMC association which can be utilized with up to 128GB modules, bought unreservedly. There is besides a four-way M.2 NVMe association that is utilized with an enlargement board to bring NVMe putting away. A lot snappier and more solid than microSD cards.

We can scarcely stand by to get one of these on our seat for testing.
