Radxa Rock3 A

Rock 3A is an enhanced version of Rock Pi 4, featuring several performance improvements and additional interfaces. The Rock 3A is powered by the RK3568 chip, which offers greater input and output capabilities. In addition to an M.2 Key M port for connecting an NVMe SSD with two PCIe 3.0 lanes, there is an M.2 Key E port connected via a single PCIe 2.0 lane. This port can also be accessed via UART and supports WiFi 6 cards for particularly fast wireless network connectivity. The RK3568 chip includes four Cortex A55 cores, with a clock speed of up to two gigahertz, along with a Mali G52 graphics solution. For storing the operating system, applications, and data, users can utilize an NVMe SSD, an eMMC module, or a traditional microSD card. For network connectivity, there is a Gigabit Ethernet port with PoE support. Video signals can be transmitted via the HDMI 2.0 port, and there is also a MIPI DSI connector. A 3.5-millimeter audio jack allows for easy connection of headsets or speakers. External peripherals and storage can be connected through two USB 2.0 and two USB 3.0 ports. A battery-powered real-time clock is included on the 85 x 54 millimeter development board. The 40 GPIO pins are color-coded and mostly compatible with Raspberry Pi and Rock Pi 4. On the software side, Debian 10 is also supported.
