Radxa’s ROCK 3C Supported by Rockchip RK3566 Processor

Radxa’s ROCK 3C (Radxa’s latest single board computer) features a Rockchip RK3566 64-bit quad-core Cortex-A55 ARM processor, 32-bit 3200Mb/s LPDDR4, and up to 4K@60 HDMI. Because of their low cost, wide range of interfaces, and top-notch design and performance, these single-board computers are perfect for use in both personal and professional endeavors. Additionally, it has a frequency of up to 1.6GHz, as well as a Mali G520 GPU and an 8TOPS NPU.

It has HDMI with a resolution of up to 4K@60, MIPI DSI and MIPI CSI, a 3.5mm jack with microphone, a USB port, GbE LAN, PCIe 2.0, and a 40-pin color extension header. Power over Ethernet (PoE) is supported by the Gigabit LAN, but an extra HAT is needed to get power from PoE. The website states that it can mechanically fit many of the existing Raspberry Pi 4 accessories.

The “Getting Started” page has a lot of information, such as what parts are needed, how to prepare, how to write an image, how to access the host, and so on. The official images for Debian Bullseye, Ubuntu Server 20.04, and Android11-20220408_1204 can be found on the Download page. There are also images from third parties and images made by the community.
