Radxa is working on a Raspberry pi like board called the Rock Pi that runs Linux or Android on a hexa-core Rockchip RK3399 SoC, starting at $39 with 1GB RAM.

The Rock Pi matches the RPi 3 layout, but unlike the RPi 3B or 3B+, the GbE port is native, giving you at least 939Mbps — about three times the bandwidth. Like the 3B+, it supports Power-over-Ethernet using the same official Raspberry Pi PoE HAT.

The Rock Pi has a microSD slot and an empty eMMC socket in addition to the M.2. You also get one of the main selling points of the RK3399: an HDMI 2.0 port. The board provides 2-lane MIPI-DSI and -CSI interfaces for dual displays and camera attachments, respectively. Other features include an audio jack with mic, an RTC, and a USB Type-C port for wide-range power.

ROCK Pi 4 comes in two models, Model A and Model B, each model has 1GB, 2GB or 4GB ram options.

Specifications listed for the Rock Pi include:

• Processor — Rockchip RK3399 (2x Cortex-A72 at up to 2.0GHz, 4x Cortex-A53 @ up to 1.5GHz); Mali-T860 MP4 GPU
• Memory/storage:
  • 1GB, 2GB, or 4GB LPDDR4 RAM (dual-channel)
